Yeah. agreed.  Just make sure that the _adapter_ can still say that it
doesn't want to be persistent; code that really, really seriously wants
to remove a persistent adapter after it's created one can do just that;

Is it possible that we can move to a new-style Componentized somewhere
else?  There are a lot of slightly-incompatible changes I'd like to
make, most especially to slotlessly subclass dict, so that the unweildy
names like 'setComponent' and 'unsetComponent' become 'x[IY] = y' and
'del x[IY]', and to save space on what should be as lightweight an
object as possible...

I do like this idea.  How do we determine if it's available though?  It
seems like there could be a lot of edge cases.

Thank you, Itamar, for doing all this work.
