Yes, and I think it's quite pointless.

The thing is, people's boot setups have probably been that way since
*long* before 2.6.9.  They continue to work, as they should, so they
aren't changed.  This is why we very rarely break boot interfaces (and
this is a user-visible interface you're talking about); we're still
supporting interfaces that have been obsolete *SINCE BEFORE 1.0 WAS
RELEASED.*

What's the upside of changing?  What's the downside?  The upside is so
infinitesimal that that leaving "ether=" in indefinitely seems like a
good move to me.
