Yes, agree.

OK, that's at least reassuring :-)

That's pretty sad, I like to have high hopes for users.

Alright, I must bow down to empirical evidence... The conceptual policy
problem is indeed what is bothering me so much, even more so than the
actual gc running on my machine.

gc.auto covering everything is good enough for me, GIT_GC_AUTO
environment variable would be better because of the way that I work. But
I can get by knowing that the gc.auto thing will at least only bite me
once per tree. And perhaps just wrap git clone in one of my scripts
that'll then do the gc.auto thing automatically.
