I'd love to have an serious answer for that question, but I havn't.
Usually I get either no answer, or something along the lines of
"-ENOTIME because of $otherwork".

Right now waiting for v6.7-final before sending a new shim.efi to
microsoft for signing and the desire to keep all archs in sync also
plays a role (I guess).

Technically there is no good reason, fedora even has a separate
shim-unsigned-$arch.rpm which could be up-to-date all the time on all
architectures, independent from the microsoft signing process.  But that
is right now at v15.6, which is not even the latest (v15.7) release.
And 15.7 is more than one year old already ...

Can understand that sentiment.  Problem is this hits the wrong people,
and the fallout goes beyond rhel + fedora because the rh team also
maintains upstream shim.

take care,
