My advise to you is to deny all support from people using the Debian version of your software and automatically close all bug tickets from Debian saying you don’t support externally patched software.
You would be far from the first to do so and it’s a completely rational and sane decision. You don’t have to engage with the insanity that Debian own policies force on its maintainers and users.
I agree that maintainers should not be expected to support patched versions of their software, but as a user I like the Debian policies you call insane. I would actually pick Debian exactly because they are cautious with the dependencies.
