Technically, pointer file indexes can be changed (in SCFG) too. Changing a sub's internal code (once the sub has messages, is in use) is not normally recommended, but I don't have the "Danger!" warnings in SCFG like I do for the pointer file index.

Correct.

Correct.

Not automatically, no, but there is that SCFG options... :-)

Correct.

SBBS only uses the sub ptridx for one use case currently, and that use case is on the chopping block (issue #832). I can leave the property/config option if there are other uses for sub's ptridx however. But I still think the sub's internal code is the best "unique identifier" for a sub-board.
