Yes, 2.2 is needed. And same here. Using it forever and no issues

Indeed, also a 2.2 thing and the biggest reason I use it honestly

Well, I _had_ some issues with that when the preserved-libs feature was
new, a few times after an emerge @preserved-rebuild nothing changed, and
emerge @preserved-libs would emerge the same stuff over and over again. I
had to delete /var/lib/portage/preserved_libs_registry manually. That
was in 2009, all was fine since then. But I fear that one day one of the
many many portage updates might introduce a nasty
bug, and portage will be broken. The chance may be small, but then
there already were over 150 portage updates in my case.

Me too. revdep-rebuild reports stuff that is broken, and I do not want to
have anything like that on my systems. What if I need such a broken
application before revdep-rebuild has fixed it? For a large package this
might take hours. And what if I run into a build problem?

Using the preserved-libs feature I feel much safer.
