Hmm, I wasn't aware of this rule.  I double checked with Rodrigo before
doing so and he thought merging a branch directly to intel-next and
gt-next with the foundational definitions and tables should be an okay
approach here (and he did an extra backmerge in preparation to make sure
it went smoothly).

Anyway, definitely my fault; I'll keep this in mind for the future.
