Filing with a STAR

That's a bit of sillyness left over from long ago. Assuming anybody
even notices the comment, they'll just assign you the full STAR route,

one reason we would put "no sids or stars" is because of the high alt. they
required which would be a problem for oxygen (for example here in Utah the
jammn four arrival puts you up at 16,000), performance wise we couldn't do
it as well as regs for o2 for crew.

usually when we did this they would clear us direct to the points or (if I
can remember) they would say "stay clear of terrain" which is basically
vectoring you and you're responsible for what's below.. (it's been awhile)

basically it's a good thing to put in if you cannot fly at those altitudes.
