Perhaps the possibility to use converters with the RF 70-200 would impair the sales of the RF 100-500 - you might get 280/5.6 or even 400/8.0, nearly same speed

The RF TC protrudes into the lens, as it did with the EF version. The RF 70-200/4 is amazingly compact, due to having the rear element much closer to the sensor. It’s literally half the length of the EF version plus RF adapter. I suspect they couldn’t make it so compact *and* compatible with a TC at the same time.

What is the length comparison at 200mm?

We use the EF version (2.8) and the ability to add a TC is great. But it's quite a heavy lens.
