I dunno; I think forbidding non-broadcast multicast addresses would be
preventing stupid things at the price of preventing clever things.

Hijacking Sun's vendor prefix is not my idea of sensible.

If you really want to do something of the sort, I'd strongly
recommending using locally-administered addresses (bit 0x02 of the
first octet set), at least by default; this strikes me as exactly the
kind of thing they're for.

No more than just adding a battery to the clock chip will.  I wouldn't
call it "trivial", but it's certainly not all that hard for anyone who
knows which end of soldering iron to hold - which, I suspect, includes
almost everyone still trying to use Suns that old.
