TL;DR: export DEB_PYTHON_INSTALL_LAYOUT=deb_system in d/rulesIs "deb_system" and not "deb" the canonical thing to use here? The GNOME team has been using "DEB_PYTHON_INSTALL_LAYOUT = deb" to work around the corresponding issue with Meson-built packages.
It's effectively the same:
# default to /usr for package builds, /usr/local otherwise
deb_build = os.environ.get('DEB_PYTHON_INSTALL_LAYOUT', 'posix_local')
if deb_build in ('deb', 'deb_system'):
prefix_scheme = 'deb_system'
else:
prefix_scheme = 'posix_local'

The deb_system is suggested for package builds:
* sysconfig: The 'posix_local' schema name is the default unless the
env var DEB_PYTHON_INSTALL_LAYOUT is set to 'deb' or 'deb_system'.
Use the latter for package buillds.

The changelog entry is the only documentation I've found for
DEB_PYTHON_INSTALL_LAYOUT.
