Ah, the Dropbox comment. You don’t even need git for that matter, you can switch between filesystem snapshots. The point is, ergonomics matter. Rebase is not ergonomic for splitting commits.
That is an absurd straw man. The point is, rebase workflow is ergonomic enough for the amount of splitting or rewording anyone realistically needs. Furthermore, knowing rebase is essential for things that these new tools can't do. It's best for people to use one familiar tool for everything IMO.
The point is this is perhaps true for you but most definitely not for others. there’s a Jevon’s paradox-like mechanic at play here which you can’t see if your axiom is ‘I don’t need this.’
