It's not really a patch. It is:

I question that statement. I have tried proposing that change multiple
times to Jörg but I haven't really even gotten a response from him
about it. I believe there are other Ubuntu developers who agree with
the Ubuntu modification and some of them are active in Debian as well.

Renaming the soname without a Provides is a problem because I
understand there are lots of third-party .deb packages which would no
longer work in Debian until those third-parties update their binary
packages. And it's not clear requiring that third-party work would be
helpful here.

Thanks,
