Yes, libsoup2 and libsoup3 are parallel-installable, both can coexist in
the same system. The only caveat is, as I mentioned in a previous email,
that having both versions loaded in the same process will result in odd
crashes and assorted failures due to symbols clashing.

Yes, I think we may need to have a separate libsoup2 package. While most
“big” packages are already supporting libsoup3 (or will soon), probably
others (like gupnp) may take longer and allowing to continue building them
with libsoup2 would be a good ide.

Cheers,
