Apologies for that incorrect statement. I had remembered a patch which
changed v3 to the v2 style of compiling out some messages (which would
have resulted in three different printk levels (compiled-in messages,
printed-by-default messages and printed-with-current-level messages)
instead of only two levels) and thought that had been committed. Maybe
it was Myles who posted that patch, I can't remember anymore.

The ROMCC interactions are still a probably valid concern.

ROM size might become a problem as well. After all, not everybody needs
all SPEW level messages compiled in.

To be honest, the longer I think about it, the more I favour the
three-level approach with the ability to compile some messages out.
