Yes, unfortunately.
If you have a package whose orig source code is large, and the delta
is representable with 1.0-with-diff (which is quite likely), then you
don't want to be reuploading the whole tarball each time. That's
wasteful of everyone's bandwidth and disk space.
So you want a representation that offers delta compression. That is
offered by the non-native formats. The non-native formats supported
by the archive are 1.0-with-diff and "3.0 (quilt)". The latter has
the problem with debian/patches/ living inside the source tree, which
is quite undesirable especially for "git-first workflows" (as the
draft text puts it).

4. We believe that there are indeed circumstances in which
1.0-with-diff is the best choice for a particular source package,
including, but not limited to, git-first packaging workflows.

Or something.

I would love for there to be something like 3.0-with-git-diff. Indeed,
I filed this wishlist bug to ask if contribution would be welcome:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1007781
but have not had any response.
The code in dpkg-source for 1.0-with-diff is quite crusty particularly
in respect of the implied behaviour wrt scanning your ".." for stuff.
The *format* of 1.0-with-diff is quite reasonable, but it lacks
support more kinds of delta. That could be done as an extension to
1.0-with-diff, but I doubt that would be a popular direction.
