I have a couple of branches that, for whatever reason, aren't headed for a merge request into master. The branches were left around for reference, in case someone wanted to pick up and continue the work. However, this too now looks very unlikely, as some of these are several years old, and of questionable value at this point.

I'm torn between deleting the branches, in an effort to not clog up git with unneeded branches, and leaving them around or perhaps archiving them somewhere, in order to not completely lose the work in case it's of value to someone down the road.

I'm curious if anyone has thoughts on the best way to proceed.
