I do use a stack and reserve an FSR exclusively as the stack pointer.  So
far 3 FSRs has worked out just fine for me.  One for the stack, one for
use by the interrupt routine (so that it doesn't have to save/restore an
FSR on interrupt), and one for the foreground code.

But they gave you one.  And an extra FSR on top of that.  And, you can
even use the stack pointer as a regular FSR if you don't want a stack
pointer.  Sounds like a good deal to me.
