Teaching uscan how to do things like git archive might be very useful.
One of my packages currently has the following, which I bet could be
replaced by a sufficiently Git-aware uscan and a bit of glue for finding
the upstream Git repository and understanding the upstream tag format
(perhaps in debian/watch?).

# These variables are used by get-orig-source, to construct dkms.conf, and
# to set the build version.  You will need to change TAG to package stable
# releases instead of experimental releases.
DEBIAN  := $(shell dpkg-parsechangelog | grep ^Version: | cut -d' ' -f2)
DEBVERS := $(shell echo '$(DEBIAN)' | cut -d- -f1)
VERSION := $(shell echo '$(DEBVERS)' | sed -e 's/[+-].*//' -e 's/~//g')
TAG     := $(shell echo 'openafs-stable-$(VERSION)' | sed 's/\./_/g')
REPO    := git://git.openafs.org/openafs.git

# Upstream does tarball releases for major releases, but not for point
# relesaes, and the tarball releases are split into src and doc and contain
# the WINNT directory.  Dropping WINNT, which is not used on Debian, saves a
# substantial amount of space in the source package, and there's no reason
# to include the files generated by regen.sh when we're going to run it
# again ourselves anyway.
#
# This rule therefore generates an upstream tarball from the upstream Git
# tag, rather than the tarball release, without the generated files that are
# not in Git and without the WINNT directory.  It assumes that git-core is
# installed and there's network connectivity to the upstream repository.
get-orig-source:
	git archive --remote='$(REPO)' --prefix='openafs_$(DEBVERS).orig/' \
	    --format=tar '$(TAG)' | tar xf -
	rm -r openafs_$(DEBVERS).orig/src/WINNT
	tar cf openafs_$(DEBVERS).orig.tar openafs_$(DEBVERS).orig
	rm -r openafs_$(DEBVERS).orig
	gzip -9 openafs_$(DEBVERS).orig.tar
