IMO, I would prefer a GIT repo which is relevant to the current development trunk (less code to maintain, less code to look through in case of bug searching, less code to build, less building time, less of all :) )
Yes, some of the mentioned packages may be required for building older TDE versions (such as 3.5.13), but we have tags and as I already said, a simple git checkout would restore your local repo to the exact point of when a particular version was tagged and built in a matter of seconds, including folders no longer present in the current repo.

Anyhow, just my 2 cents.
