Just looked at hg absorb. It seems like a very useful feature but I understand it is an extension by Facebook. Can't someone make a similar extension for git?

...and I just found it: https://github.com/tummychow/git-absorb

As a daily hg-git user, could you elaborate on (2)?

Hopefully this: https://www.mercurial-scm.org/pipermail/mercurial-devel/2019...

That would be helpful

I use hg-git to put all my Mercurial based projects on Github.

But the last OpenSUSE update installed Mercurial 5, but left the old hg-git for Mercurial 4. Now it does not work anymore.

On Windows it is broken since TortoiseHG 4.5.2

TortoiseHG is really cool

I used to use it all the time on linux.

Unfortunately the OpenSUSE update also removed it. Completely, it is not even listed in the package management anymore.

No one wants to maintain non-mainstream software
