  I agree when you are writing a library code. But if
the environment is fix at a particular bank setting
RP0 and RP1 does make sense sometimes. Best bet it is
use macro to eliminate unwanted instruction like the
extra pagesel or banksel. But for testing and in the
development. Use pagesel and banksel for the variables
to NOT cause a headache to ensure that it gets the
variable correctly. Once the code needs trimming than
you have to revisit your work if it is feasible to cut
the redundant ins. In short, directly setting RP1 and
RP0 in you code src is like specific the req bank and
does not allow adjusting the bank unless you change
all your bank settings again.......
