Although it's certainly a step up from the previously hard-coded default, I would argue that the most desired behavior is to follow the permissions already set up. If the library is setup to be group-writable then the package should be installed group-writable. The point is that anything else makes less sense - the user can still use rm -rf and re-install it even if the package is not writable. It's just update.packages() that fails.
One could also consider respecting the umask which is ignored in the
older behaviour, ignore in what was just committed, and ignored in what you
suggest here. Not exactly right either.
But up until right now I could not update a package a colleague installed,
and vice versa -- unless we sudo.
