Yeah, sounds reasonable.
For MC2, I created a package called SystemEditor that uses roughly
the same approach. It presents an "editing" interface with the same
protocol as the real system. I'm sure it's not quite identical, but
it's close enough that MC2 can have atomic loading turned on or off
with a one-line change.
It probably wouldn't be much work to make MC1 load definitions
through SystemEditor rather than SystemDictionary. More work would
have to go into SystemEditor to make it solid enough for production
use, but it's still probably less work than starting from scratch.
