SimFactory 3 supports multiple user-defined "applications", of which Cactus is just one.  As such, Cactus-specific knowledge is compartmentalised.  In my opinion, simfactory should know as little about cactus as possible; we will add convenience features on top of the cactus build system because the cactus build system lacks them, but this is a pragmatic solution – ideally the cactus build system would be improved and this extra layer could be removed from simfactory, but that is more complicated as the cactus make system is quite "involved".

Yes, we have decided to do that, and also for the thornlist.  It was a design decision of versions 1 and 2 that the options should be explicitly imported to the configuration, rather than pointing the configuration to the external file, but I think this leads to too much confusion.
