It's less about "ASAP" and more about "Do you think it's ready to go in
right now in 2.27?"

By submitting it for 2.27 you have the following consequences:

* You need to convince maintainers for review during a precious period
  of time when we're preparing the release and handling bugs.

* You need to have confidence your port is ready and you haven't made
  any real ABI mistakes. Any last minute mistakes that slip through
  will become permanent ABI artifacts for the port.

Instead if you submit your patches for 2.28 you have the following

* The good will of the maintainers who know they can review your
  patches with time, looking for ABI issues.

* Get the patches into 2.28 early, and allow for testing before
  the 2.28 release on August 1st 2018. This will iron out any ABI
  issues before release.

I have purposely slanted my bias in this explanation :-)
