I don't think that's true. I think the fundamental reason is that
there is no *really good* solution to the problem of maintaining a
delta branch over a long period.
There have been a number of attempts, and relevant tools, including
things like topgit and stgit, as well as gbp pq, and of course my own
git-debrebase. This is a hard problem which no-one has a good answer
to. So in the absence of one good answer, people choose the bad
answer they prefer.

By "git interface" I think you mean git branch and tree formats?
If so, we have written them up, here:

dgit has tackled this problem head-on. We have given names to these
git formats, and can convert each of them to a canonical git form.
We call this form the "dgit view". It has the maintainer history as
ancestor, and is treesame to the results of `dpkg-source -x`
(excpet that it doesn't have a `.pc` directory). It's what you get
from `dgit clone`.
So, yes, this is the hard part. But it is solved.
tag2upload will reuse that functionality.
(So, where that table has "not supported" for "dgit push quilt mode",
tag2upload will not support it either.)
