We'd want Tres's opinion on that. Tres, could you expand a bit on what
exactly you mean by #33 ? I see it only as a discussion-specific UI
problem. To me the information still should be stored in the TI, and
available in its list of properties.

Well that tab is only important for CMF developers or site configurators
anyway, and it centralizes information. I hardly see it as bloat.

Of course and in 99% of cases an installer would do it.

For me SimpleItemWithProperties is nice when you *know* you don't want
to change the schema properties. IMHO that's not the case for
TypeInformation.
