It's also relevant for the other way round, i.e. the developer has provided only an executable compiled for standard FPU (because, for instance, the program isn't developed anymore) which calls a (system) library that on the user's system is compiled for SPE. This is assuming Hyperion will provide the Tabor version of OS4 compiled for SPE in the relevant parts.
Or, even better, imagine an executable compiled for standard FPU or SPE, which calls two different libraries, one compiled for standard FPU and the other one for SPE.
In that case could a blacklist be implemented, similar to the one for using or not 68k JIT emulation? SPE and FPU libraries are supplied, SPE ones are used by default unless you blacklist the program so it uses FPU ones or viceversa.
