Any Gentoo users interested in a slotted PostgreSQL ebuild?

Hello folks.

Are there any Gentoo users here?

Do you wish the PostgreSQL ebuild made use of SLOTS?
- to allow installing of major versions together (eg. 7.3 and 7.4 on the
same host)
- to ease migration of databases to new major versions (where a
dump/reload is required)

I've started a thread at:
http://bugs.gentoo.org/show_bug.cgi?id=42894

With a initial plan for relocation of files to support slotting.
Comments, suggestions, corrections, or messages to say it's a silly idea
(and why)
would be very much appreciated before I attempt this next week.

Cheers
