I think this is a very good idea... I have been seeing requests for this
kind of IJ commands from the beginning of Derby project. :-)  I believe
these can be implemented as IJ only commands very easily.

Are you thinking of adding them as SQL statements that engine
recognises? I would rather see them as IJ commands, that only IJ
understands. There are several IJ commands that are not recognised in
engine... like GET CURSOR for example. It should be possible to add
several new IJ commands that translate into regular SQL statements
against system tables to display required information.
