I don't speak for Palmer nor SiFive, but from my point of view the

Well, I'd suggest daily (at least) submissions of revised versions of the
port until we converge on something with no more issues found in review
and that has sufficiently good test results for all the supported
configurations. Even if a port variant is known to build OK but the tests
are still running, it may be worth posting the patches for review so
issues are found sooner.
It's up to the people submitting the port what configurations are
supported, now or in the future - there could be from 1 to 12 ABIs, as I
understand it. But there should be some evidence (in the form of
testsuite results) that the supported ABIs are actually functional at the
time they are added, and should not be code that's purely for unsupported
ABIs (such code can be added later as and when support for those ABIs is
added).
