I forgot to add the bug-link:

https://bugs.gentoo.org/show_bug.cgi?id=465772

There you can find at least my rough estimates of how many ebuilds
are directly affected. Shortly saying, if we fix PMS, we need to fix,
say, 200 ebuilds. If we leave it as is, we have around 1750 obviously
broken ebuilds + over 3000 if we count DESTDIR=${D}. Not to mention all
the hidden issues.
