But in the end, that's precisely what you propose to do yourself with
"partial stdlib upgrades"!

It's just that you trust yourself more than you trust "any project".
But that just doesn't fly from the point of the third party clients of
the stdlib.  Either stability of any particular version's stdlib
applies to the stdlib developers too, or it doesn't really apply at
all.
