Yes - because, for example, squid I'm building with extra settings so I
want my version to be higher than the corresponding buster/bullseye
version. There is no backporting involved.

But I didn't know ~ was different. Indeed, for packages I've backported
and want return to mainline eventually it sounds like what I should be
doing for backported packages.

Indeed, sounds perfect. Thank you. I'll have to rework my scripts so I
can choose ~ or + depending on whether I'm backporting a higher version
from a future release or patching the current release.

I already have config for $source_distribution and $target_distribution
so I might be able to automate the patch version.

Thats the bit of magic I needed. Thanks!
