Lenses exist in a variety of sizes and speeds in order to provide something for everyone. So having more options certainly shouldn't evoke a "backlash." It should be welcomed by all because it helps draw more users into a system.
The truth is... lenses exist in a wide range of sizes because customers want them.
There was no "backlash" when Toyota started selling huge SUVs because they continued to make small economy cars too. You can buy whichever one suits your needs the best.
And if your argument is "these products I don't want are using valuable company resources that should be devoted to the products I do want" then perhaps Canon should stop making printers, Olympus should stop making medical devices, Panasonic should stop making rice cookers, and Sony should stop making video game consoles.
I just don't see any downside to having more buying choices. These are simply different products for different customers.
I hate to query a wonderfully sensible and balanced post. But if you will indulge me with expressing a theory
You are basically correct across all the systems we have choice, You can assemble a wonderful light MFT system to cover a huge range of focal lengths. Why does it matter that some micro four thirds are heavy, It doesn't
I suppose Nikon mirror less stands out a system with less choice for light a system. I suppose that means that if you want a light mirror less system then Nikon isn't the way to go. No one promised it would be light but maybe that's what people were hoping for
You raise an interesting question that deserves an answer.
"Small and light" are relative terms. It really should be "smaller and lighter" than some existing alternative.
A Nikon Z7 really IS quite a bit smaller and lighter than a Nikon D850, even if that difference shrinks a little once you add equivalent lenses to both. So Nikon has now given their customers another option.
The truth is... no full frame system is very small or very light. And this goes back to simple physics. Larger sensors require larger lenses, even if the camera body can be shrunk considerably. But a Z7 and a D850 will often serve the same purpose, with one being significantly larger and heavier than the other. And that is why it becomes an appealing alternative for some users.
Within each format there are choices available that vary in size and weight. Probably the most extreme example of this is M4/3, where bodies can range in weight from a 204 gram Panasonic GM1 to a 997 gram Olympus E-M1X.
And there are customers for both cameras. Each size has it's own proponents.
So, I would say that Nikon still offers their customers a reasonable choice. If some were hoping for a bigger difference in size, than perhaps they failed to understand the that larger sensors require larger lenses. Because the Z7 body certainly is smaller than D850.
If that customer really needs a smaller sized camera, then they might be better off switching to another system. But that would only achieve a marginal difference at a very high cost. Or, they could switch to a crop sensored system to achieve a bigger size difference, but that would come at a cost too. Not only in price, but in utility as well.
