This is great news.  I'll look into updating some of the packages that are
called out as out of date in the ticket.

I think that's a reasonable approach.  It looks like the SCL guidelines are
still in the works, but we can probably get started using them anyway.

Do you think should try to get the packages into Fedora proper once the SCL
process is defined?  I think that would mean some manual work for each
package (getting it reviewed, making sure the generated spec conforms to
whatever packaging guidelines apply, etc)

Similarly, does it make sense to see if the OSRF wants to take care of
building and maintaining Fedora packages in tandem with their Ubuntu
release process?  SCLs are kind of designed to make it easier for third
party distributors to create and provide sane packages, and if bloom knows
how to do so then it might not be so bad.  On the other hand, keeping such
a large packageset in sync with two distributions is probably going to be a
lot of work, and probably isn't going to scale if they ever want to add
official builds for more distributions in the future.  Keeping packages
within the Fedora ecosystem means you get the benefit of warnings if
dependencies shift from underneath you, coordinated updates, etc.

I think that it would be good to coordinate with the OSRF on this, and see
if they plan on providing packages themselves.  If not, we need to
coordinate the best way to get their packages into Fedora (copr, fedora
SCL, etc.)
