Not so, there are a lot of things where USE="test" pulls in extra
dependencies, dev-perl/* is rife with them.
And I've seen some things where USE=test changes behaviour of the
compile phase sufficient that enabling USE=test *could* change the
code compiled as well.
But I think I see where you're comming from.
I just can't see a reasonable cover-all approach that wouldn't really
be a large nasty package-manager specific hack.

And besides, I'll reinstall a package if so much as the MD5 changes
due to somebody adding keywording for an arch I don't use ;)
I think what would be more practical is a sane way to enable
FEATURES="" on a per-package level like USE flags in portage, then you
could enable FEATURES="test" for that one package and it would always
build that package with USE="test"
Paludis does this already via an extended use.conf syntax:
=dev-foo/bar-1.2 flag -otherflag BUILD_OPTIONS: optional_tests
LINGUAS: en
Perhaps portage does this already and I'm hiding under a rock, but I
haven't seen it, and I've just cheated the system with
linguas_en
and other similar manual USE_EXPAND tricks in my package.use
