We (Ardour) abandoned it, because the universal experience of non-programmers was that they had no idea how to even begin to use this sort of feature. The majority of DAW users don't come ready to deal with the complexities of a branching workflow, or even a desire to learn it.
There is at least one band out of Madison, WI that uses/used git with Ardour during the height of the pandemic to facilitate remote collaboration on new pieces. They gave a talk (and played) at the Ubuntu Summit in Prague last year.
As a very entrenched Reaper user, I haven’t tried Ardour, but I’m glad it exists and continues to exist. Thank you for your work :)
Turns out their pivot to being Netflix for samples/plugins is more in demand :)
`bup` notionally does this a lot better, or git-lfs.

git really needs textual representation for any kind of meaningful commit, and binaries totally break that.
This is precisely what git does NOT do.
The other thing I saw the other day that I thought was cool was a reverb plugin that uses your GPU. Seems like the next step for modeling could easily be in that direction. Especially since the bar there is low, pretty much just the positively ancient UAD hardware acceleration cards, although UAD themselves seem to be going the opposite way and pushing native stuff now.
