/boot size

For RHEL7, I've got a bug about needing to make /boot larger.  For once,
it's not a private bug so I can even show you:

https://bugzilla.redhat.com/show_bug.cgi?id=1270883

The fix is to make /boot larger so more kernels can fit, say, 1GB.  It's
not a big change but it raises a bigger point.  If I make this change
just for rhel7-branch, it will be a regression when we get to RHEL8.  To
prevent that from happening, I also need to make this change on master.
But that will affect all new installs of Fedora.

Does anyone think that is going to be a problem?  Does it need to be
discussed more widely first?
