[gentoo-dev] collision-protect -> protect-owned ?

It came up again with <https://bugs.gentoo.org/show_bug.cgi?id=449918>,
and I think it's worth to think about a better fix. I still keep hitting
mysterious collisions with orphaned files from time to time.

How about switching the developer profile from collision-protect to
protect-owned, and proceeding with enabling protect-owned by default for
all profiles? (not all developers are using the developer profile)
