Please note this is not always true.
Power pins can be very important for functionality. I.E many different
supply voltages or filtering of supply for analog parts or routing of
supply.

We need better support for multi-component symbols, but we need better
support for visible/hidden power pins (of slotted symbols) too. Maybe a
switch which can hide the pins. (And we need support for parts with
multiple power pins -- some fast OpAmps have 4 pins for VCC and 4 for
VEE -- internally connected.)
