Perhaps you could convert this into a pkg.e2fsprogs.nofuse build profile?
<https://wiki.debian.org/BuildProfileSpec>
This would look something like the attached (untested!) patches.
The intention seems to be that build profiles are how this is done
automatically or near-automatically in future. dbus and glib2.0 are
examples of packages where I've made use of build profiles to cut off
non-essential functionality for bootstrapping (they're significantly
further up the stack than e2fsprogs, but were involved in a cycle in
the past).
Having nodoc and noudeb build profiles (assuming the package has
documentation and udebs) also makes local test-builds a lot faster for
many packages, which is very convenient when testing functional changes.

You can skip binary packages on a per-build-profile basis without having
to generate debian/control from debian/control.in. After doing that,
it's often convenient to write build profile checks in debian/rules as
a check for "are we building package foo?" rather than "are we using
build profile foo?", like this in dbus:
binaries := $(shell dh_listpackages)
[...]
ifneq ($(filter dbus-udeb,$(binaries)),)
# udeb build
make -C debian/build-udeb install-exec
DESTDIR=$(CURDIR)/debian/tmp-udeb
endif

These sound like excellent use-cases for build profiles.

Less so these days - I believe there are tools being developed that can
automatically break cycles by building cut-down packages (no documentation,
no FUSE, etc.) and later replacing them with a fully-featured version.

This is a non-standard build profile, but could be used during
bootstrapping.

This is a standard build profile. Not building udebs speeds up test
builds if only the full-fat version is going to be tested anyway.
