  • Facebook does not use Git due to scale issues with their large monorepo, instead opting for Mercurial.
  • Mercurial may be a better option for large monorepos, but Git has made improvements to support them better.
  • Despite some drawbacks, Git usage remains dominant with 93.87% share, due to familiarity, additional tools, and industry trends.

Does that not happen with Mercurial? If not that seems like a point against it.

I’m confused, the behavior you just said was “exactly the same in git” is now a problem for Mercurial?

I thought it was exactly the same based on the description.
