I am aware that  I  cannot  mix  this  WITHIN  ONE  application,  for
instance  compiling  the  app  with  soft-float and linking against a
library that uses the kernel FPU emulation.

Are there really problems when running soft-float only  and  FPU  emu
only applications on the same machine? I did not expect any...

Anyone who isn't confused here doesn't really know what's going on.
