Here's my suggestion posted previouly to the Gentoo-user list. I think this 
solution prevents the problems associated with branches, while not locking 
anyone into a system that they're not happy with.

I propose the addition of stability levels to gentoo. This would allow users 
to run a bit behind the state-of-the-art, while still taking advantage of the 
features Portage provides.

The levels I propose would be something like:
Stable: Conservative, for people who require extreme stability.
Standard: The base level. A few weeks behind what we have today.
Current: Gentoo as we know it today. For people who are a bit more 
     adventurous, but aren't willing to accept betas.
Devel: beta packages are installed by default. Only for the most adventurous.

In addition, all packages at a fixed version level (ie 1.0) would be flagged 
as such, allowing a user to recreate that version number months down the 
road.

This doesn't lock people in to a given stability level, it only changes the 
default behavior of the installer & emerge. The stability level could always 
be overridden, just by specifying a newer (or older) version of a particular 
package.

These features should be easy to implement on top of the current package mask 
system (though I should state: I am not a programmer, and am not very 
familiar with the internal workings of Portage). 

This should not be viewed as creating 'branches'. Instead, it creates 
'reference points'. All development takes place at the devel level. From 
there, the only maintenance required would be gradually changing the masks to 
move packages in to the progressively more stable environments. This will 
require some extra work on behalf of the package maintainers, but it 
shouldn't require more then maybe 30 minutes of work a month on actively 
developed packages (even less on the vast majority of packages).

A more flexible package management system simplifies things greatly. Many 
users don't want a bleeding edge system. How often are significant bugs 
discovered only after a upgrade has been available for weeks? And in the 
three months or so I've been using Gentoo, I've already seen at least a 
couple of times when packages were accidentally unmasked prematurely.

Having stability levels allow the adventurous to run a bleeding edge system, 
the middle 80% can run a system that is maybe a few weeks behind the bleeding 
edge. And those people who need a bit more stability can run stable. 

Gentoo's ease of management makes it ideal in many ways for an office 
environment and servers, but when you have users relying on the computers 
working every morning when they get there, bleeding edge doesn't cut it. 
Having a stable flag makes this sort of system manageable.
