Thats why you also add a regular diode and compensate with a lesser
value zener. I believe this was already mentioned. But in assembly, it
is easy for a newbie to be confused about how a zener works
differently than a regular diode.

Yes there is no regulation, but is it required? It depends on the
ciruit and I don't think that a blink-a-led needs regulation. PICs do
not always need regulation, especially with such a wide operating
voltage range of most PICs. I have found the INTRC to be very
forgiving of supply variation and have not had a PIC lock up due to
supply ripple.

9v is the de-facto standard power supply for newbies. What could be
easier for a newbie to diagnose and replace?
