UML is coded, most other sheets are defined as XML.
I would like to know if the developers have any ideas as to how the UML
shapes could be transitioned at least partially to XML.

i dont really know about the programmed shapes such as UML, undoubtedly
more connection points could be programmed into them but they are not
written as XML and my understanding is that you could not therefore change
them the XML way.

see above.

Post a tarball anywhere you like.
if you would like the shapes to be included and distributed with Dia post
a link the mailinglist (do not mail attachments to the list please) or you
could create a bugzilla report and attacha  tarball of your shapes to the
report.

Please make sure that you give clear and thorough permission for Dia to
use the shapes provided, previous shapes had to be removed from Dia
not because of any object but because there was no clear permission and
the author was uncontactable.
(I suspect that there is no single one copyright holder of Dia which would
make future changes of licensing ridiculously difficult, in the unlikely
even they were needed).

Good luck
