I believe that the original intent of the NOTICE condition type was to
make it something disjoint from SEVERE-CONDITION and WARNING, right?
As Pitman pointed out some time ago, introducing a new condition type
requires more than just saying it exists.  Making the condition type
used for these kinds of compiler diagnostics a subtype of WARNING has
the advantage of simplicity -- it can simply borrow all the same
mechanisms as WARNING conditions, including the WARN function and the
MUFFLE-WARNING restart to disable printing of messages.  Doing all of
this from scratch for a disjoint condition type would be more
complicated than I have the time to figure out right now.  If you feel
ambitious enough to tackle this, feel free.  I agree that there is no
inherent reason why we cannot define a new condition type on our own.
