New description:

 another aspect of "how to publish our puppet repos" and how to collaborate
 is how to manage sub-repositories. expanding on the "mono-repo" problem
 discussed in #29387, i have found the following options:

  1. current "monorepo" approach
  2. pure [librarian https://librarian-puppet.com/] / r10k
  3. submodules
  4. git subtree: ​https://github.com/apenwarr/git-subtree
  5. git subtree (same?):
 ​https://github.com/git/git/blob/master/contrib/subtree/git-subtree.txt
  6. git subrepo ​https://github.com/ingydotnet/git-subrepo
  7. "myrepos": ​https://myrepos.branchable.com/

 i'll add more as i find them here. i should probably make a more detailed
 review of the advantages/inconvenients of all of those...

Comment (by anarcat):

 one problem with librarian right now is that `librarian update` clears any
 existing git subrepo and re-clones it from scratch. if you have temporary
 branches that were not pushed remotely, all of those are lost forever.
 that's really bad and annoying!
