I moved the discussion on -dev since it should be the right place to 
discuss this.

I focused on one of the issues I found in the current -9999 and that 
your -scm proposal doesn't solve and that annoys me a bit.

upstream is an undefined entity. We knows already upstreams that follow 
a specific version numbering, that tag their release before time and 
that even have playground branches where interesting&scary thing happen, 
upstreams that keep everything on a single branch and people doing 
something insane or worse.

so NOTHING could represent something unpredictable.

Pardon, typo, I meant emerging.

That doesn't cover the "pu" case brought up by ferdy or another case in 
which you plan to track a branch that isn't a version branch or hasn't a 
version target, if you want to be strict. So scm solve the same problem 
_live solves or plain usage of "property live" within current ebuilds 
solves.

In short any proposal that includes the "live property" gives you the 
same benefits. The live template proposal gives added value to the thing 
since it makes possible do more and something more useful since the 
reduced scope of interest tracking upstream has in the end.
