So the deal we've had with the Renesas guys is that we've been allowing
some legacy code to go in, but that we got a handshake earlier this year
that they were done adding legacy code as of 3.13 / end of the year, and
they will now start focusing on enabling multiplatform and modernizing
the shmobile platform.

So, is this one of the few straggling drivers still looking to go in? Or
are you anticipating more of this over time? I don't want to see much
more of this added right before it's time to cleanup.
