Not so much of an issue of not being able to, more of an issue of having a 30-40 mm tube being clamped supporting a moment arm 1 or 2 m away. Doing any work at the ends of your bike make the whole thing bounce and jerk. It’s a huge moment on a small mounting point. It’s just a very bad design.
It’s like people who don’t use their parking brake. I absolutely cringe every time I see someone pull into a slightly sloped parking spot, stop, and I see the vehicle roll back and bounce from every shaft and gear being torqued up the whazzhoo in the transmission. Bad bad bad. But some will argue that “oh it’s designed for that”. Doesn’t matter - I don’t like when machines or structures “feel bad”.
You might want to check out what are generally known as team repair stands. They tend to be a bit more expensive, and not really quite as useful as a regularly stand that clamps to the seat post, but they address your concern by mounting the bike from the forks and bottom bracket.
Most bike maintenance doesn't require high torques and the bike is sufficiently stiff that it doesn't really bounce and jerk at all. The ease of adjusting the position of the bike to what you are working on or cleaning makes the traditional repair stand well worthwhile in my opinion and is a benefit that you simply don't get with the team-style stands. Removing pedals is easier off the stand in my opinion, and maybe working on the bottom bracket? I don't know, as that's not work I've tackled myself yet.
