Yes I am aware of this. The point of bringing up what is going into
RHEL7 was to get a flavour of what RedHat consider stable enough to push
out into a supported enterprise product.

I always ran my GPFS/Samba/CTDB clusters by taking a stock RHEL Samba,
and patching the spec file to build the vfs_gpfs module possibly with
extra patches to the vfs_gpfs module for bug fixes against the GPFS
version running on the cluster and have it produce a suitable RPM with
just the vfs_gpfs module that I could then load into the stock RHEL

It would appear that RedHat are doing something similar in RHEL7 with a
vfs_glusterfs RPM for Samba.

Of course even with CTDB in Samba you are still going to need to do some
level of rebuilding because you won't get the vfs_gpfs module otherwise.
