How should it behave? run

You want to keep state so that only incremental updates hove te be

I found a nice solution to this month ago. Have a look at

It will
a) checkout sources
b) create a .tar.gz (because this is the only reliable way to trigger
  rebuilds. Nix does not always notice that directory contents
  changerebuilds. Nix does not always notice that directory contents
  change
c) optionally upload a snapshot to a SSH server

It will also automatically keep an update log.

It is supported by me. Example: haxeDist in all-packages.nix.

Run for a new feature. Spend the time on proposing it - wait for replies
(which don't happen on this list ..).

Or use what has been working for me for month now.

Do whatever you have to do. I want to remind you that there is an
existing solution which gets your job done.
