If I want to retain some shadow detail as well as bring down the highlights - depending on what I think is important to me I may well focus on the shadows, accepting that highlights will go wherever they go and manage that as best I can using ND grads
You can't assess shadow detail in a raw file from looking at a histogram derived from the JPEG image.
Sure you can! While it may not be exact, it's close enough.
I guess that when you want “close enough” for your own taste and do not care much about clipping blacks or blowing out highlights …then you’re probably right. That’s not everyone’s cup of tea though.
I care about the final product, and the histogram gives me enough information to decide exposure. I don't care about preserving details that don't matter and that nobody will ever see. The histogram and clipping alert get me where I need to be for my work, quickly and easily every time.

How can you tell what the raw shadow detail is going to look like when lifted three stops from the JPEG histogram that crams that information into the leftmost few pixels?
I have no idea what you are talking about here, and it doesn't matter for my work. I do headshots, portraits, environmental work, street, and never, ever, have I asked myself anything like this. As I said elsewhere, understanding the technicals is important to a point. There is absolutely zero need to ask the above question to achieve great results.

The contrast of current EVFs and LCDs is quite bad. Often, I cannot see any details in deep shadows, but I can extract plenty in the post. I cannot see anything useful about shadows when looking at the histogram.
Shadows are meant to be... Shadows! What happens there happens. Make a decision on what's most important - overall exposure, preserving highlights, or shadows, and then shoot appropriately.
In my case, if I have to limit anything, it's usually highlights. Shadows fall where they do. They are shadows, after all. If I want to look into the shadows, or expose for the shadows, well, then I meter for that. It's very easy to see that in the histogram.
This forum tends to obsess far too much about the technicalities of things, while spending hardly any time at all on practical approaches to getting results. Most photographers are concerned with results, not necessarily whether they are clipping some blacks or blowing out some highlights that we can't see, anyway.
Blacks do not clip. It has been repeatedly mentioned that only preserving
relevant highlights matters.
What is relevant and whom are we speaking about matters in context.
Capturing all of the highlight and shadow detail also means low contrast images that lay flat on the page. Doing so also ignores how an image is viewed. Very seldom do we need to see into the shadows or want to examine the fine hairline scratches in a piece of stainless steel that's reflecting a beam of sunlight. That's hardly what's important in a photo.
I shoot using Fuji's film simulations. The histograms are perfectly accurate and acceptable, allowing me to capture in-camera exactly what I intended.
Fuji's histograms are acceptable, but certainly not
perfectly accurate, unless you are shooting only JPEGs.
One doesn't need perfect accuracy to create art. One might argue the opposite.
Obsessing over a little bit of lost shadow or highlight detail is, in my humble opinion, putting focus on exactly the wrong thing.
The focus in this thread is on how to meter.
Thank you for the reminder. I'm discussing how I meter using the histogram, and what is relevant and important to my work. I believe that is within the scope of this discussion. Metering doesn't need to be as complicated as some make it out to be.
