It's not mutually exclusive. If people are using this in production unaware that they can't do transaction recovery then i'm quite keen to know about it and (if necessary) point them at the relevant config.

I don't think it's a safe assumption though - you can define an activationSpec without a corresponding MCF, so there's no guarantee you can get the necessary information to drive recovery

12.5.2 reads to me as if the server must call ResourceAdapter.getXAResources(...) to do recovery, although there may be something elsewhere that overrides that section - it's been a while since I read the spec in detail.
