Sure, but you pay that hit either way. Real-world performance is always usage based: the assumption that uv makes is that people run (i.e. import) packages more often than they install them, so amortizing at the point of the import machinery is better for the mean user.
(This assumption is not universal, naturally!)
Ummm, your comment is backwards, right?
Which part? The assumption is that when you `$TOOL install $PACKAGE`, you run (i.e. import) `$PACKAGE` more than you re-install it. So there's no point in slowing down (relatively less common) installation events when you can pay the cost once on import.
(The key part being that 'less common' doesn't mean a non-trivial amount of time.)
Why would you want to slow down the more common thing instead of the less common thing? I'm not following that at all. That's why I asked if that's backwards.
