No, the reverse. If there is no message then the viewers that don't
implement old broken stuff are seen to be at fault. If there is a
message then its clear which content is broken.

Remember this isn't 'legacy' as in 'it was previously a standard' but
legacy as in 'nonstandard, proprietary extensions, relying on bugs in
a particular viewer'.

And without an error message, yes, new viewers will be seen to be at
fault. So they will be under pressure to reverse engineer bugs etc and
the format gets defined by reverse engineering and impenetrable
hueristics, not by the spec. See html browsers for where that  ends
up. The whoole mess of reverse engineered bu-alikes so so frasgile
that any forward movement in terms of spec compliance becomes
impossible, hence the sorry state of html browsers today that have not
improved significantly in three or four years.
