There can be other reasons to keep the history in /some/ publicly
accessible repo (maybe not in the mainline though):
- Changelogs sometimes explain why something was written in a
specific way, which may not be obvious from the code or comments.
- Some modifications during mainline merge preparation, e.g.
simplifications, may turn out undesirable later and one wants to
revert some of such modifications.
