But it seems to me that overlays are the primary use case for commits to 
public trees other than gentoo first.  Otherwise, the whole rebase-vs-
merge problem goes away, because the first public commit is to the gentoo 
tree.  But especially with overlays (like kde) that have an overlay-
first, test, then gentoo-tree, policy, that public overlay tree (which is 
already in git) is part of the process.  Commits MUST go thru the overlay 
to get to the tree, and that overlay is public, so constant rebasing is a 
definite no-no.

Which unless your workaround idea works, pretty much leaves us with merge-
commits as a necessity.  (Which of course, as Ciaran pointed out, are 
part of the point of git, such that running git without merge-commits 
defeats part of the purpose of the whole exercise.)
