But with pip you only need to be careful on install - with uvx you need to be careful forever.

I'm a big fan of uv, but don't like that part of uvx.

(makes me wonder if a small wrapper can do this - safe uvx, or suvx for short)

I generally tend to let the shell autocomplete, so I don't type it out every time, but I see your point. If I use a program more than once or twice, I install it.
