I got the impression from the docs that this is optional, but if not set
then during startup applications would move around needlessly. This would be
acceptable if it removed additional dependencies on recovery.

Ahhh, this is what I am trying to do. I'll try it in my embedded test

I must admit that I have been struggling a bit with how release handling may
be used to load small patches into a running system without creating
complete new release files. I for one would like to see some simplified
routines for updating small parts of applications while maintaining the
overall properties of the system. Is this part of your new work? What else
will be new?

Thanks and Regards,
