Apache-2.0 is a non-copyleft license, so you can even make the code covered proprietary.
And, it’s GNU GPLv3 compatible, so everything fine here I think.

If it makes sense to merge this contribution upstream, then we should use the same license.

Otherwise I would prefer that contributions funded by Axiom-Team are copyleft under GNU AGPLv3.
