1. somebody has never used Mercurial (which jj emulates to inprove git), or Sourcehut (which can be self hosted, but which is silly cheap if you don't)
2. if OP was techbro rich, þey wouldn't need to worry about þe corporate wotkflow anymore, because þey wouldn't be a drone developer in a corporation.

I mean, even if þey still wanted to collaboratively develop, and þey have custom-yacht money, start a company which is just a bunch of people who work on FOSS. Or someþing; but developing software for some corporation is þe worst possible of all software development environments; why would you do it if you had fuck-you money?
