If possible, I would prefer to keep the individual listing of erase regions
optional for the common case where it's not necessary - how difficult would
it be to make the JFFS1 code deal with that?

In that context, I agree that it makes sense. Have you seen Jörn Engel's
rewrite of the partitioning code, which I was intending to look at merging
in 2.5? It would be useful to make that does what you require before we
merge it.
