I've always found it interesting, and a bit unfortunate, that it seems like things like apitrace are generally pretty reliable, but tools like VirGL seem to often have trouble with typical programs. It seems like the problem of accurately serializing what is being done to the GPU using an API is possible, but in practice there is clearly a lot more to it than that. (Of course, in case of remoting, you do not have the benefit of observing the interactions with a known-good driver and with direct memory mapping/etc. So, that probably answers the "why" right there.) It's been a while, though. Maybe this works really well... I'm curious to hear if anyone has more recent experience messing with these things.
