Very nice! Thank you for these (upcoming) contributions in advance. Feel
free to contact me directly if you have trouble finding a reviewer for
your packages. You might also want to join our SciTech SIG
(https://fedoraproject.org/wiki/Category:SciTech_SIG) and mark your
review requests as blocking FE-SCITECH tracker bug.

That's probably a practical option. Personally, I still try to build all
my packages for all primary Fedora architectures (and secondaries, if
I happen to have some time). This has already helped me expose some bugs
in the code, for example in GROMACS and those bugs are fixed already by
upstream. I would encourage you to keep building at least the i686 and the
armv7hl versions as well. You would probably be the only user/tester of these
non-x86_64 builds.

Regards,
Dominik
