Of course.

Maybe not as cool as git but still tags and branches.

This will be hell to maintain. Who / when to deprecate older versions 
that does not compile with anything new? Shall it be kept for 
ten years like you seem to suggest?

Bit rot tends to start showing up in less than a year.

for *that* particular version and patch set.

That is tags and releases. No need to have more than one version 
of the packages for that.

distribution or arch?

Then you add that package (or do you mean version? then you bump it and make 
sure it goes through the test runs) and then add your specific patches 
if it's nessesary.

it can be overridden in the .mk file and then tagged with ignore in 
the SCM so it won't be overwritten by the next update.

And then we end up with so many versions it'll hurt, alot.

As mentioned; Debian manages without and doing this will complicate
way too much.

This didn't make sense. Previous versions of a package 
or "distribution"?

Whitch is exactly why we don't need this.
