Yes. https://wiki.debian.org/DontBreakDebian . Don't mix in PPAs if you
do not exactly know why.

Also true.

I think about it. Currently we host it on a server that already uses
80/443 for something else.

One additional way would be to extract the tarball on a machine you can
access SPAAS and where you have the exact same kernel version as on the
destination. Then build it, which will fetch a SPAAS generated patch.
Then generate the dkms package from that and dpkg -i it. This then finds
the patch in the cache and does not try to fetch it. Not very nice, just
saying it could be done like this.

What some devs, me included, did for some time was to use a 'spatch'
that was in fact a Docker container containing an spatch recent enough.
You most likely don't want that in production either, but it could be
used instead of SPAAS for the above described tarball-repacking.

Best, rck
