I have removed more exhaust studs than I care to remember over the years
and have 'never' seen or heard of a pressed fit exhaust stud in any
vehicle I have been exposed to.
I also have removed a couple 80's YJ ones...
The replacements come in kits with the special brass nuts.

You must be thinking about something else.
We're talking about the manifold to pipe connector.
Here's the version NAPA sells for the TJ, part BK 6003227:

Good lord, you are now telling me the $tealerships just came up with
another way to screw you out of big bucks by replacing a screw stud with
a press fit that needs a freaking machine shop to fix? It also has what
looks like a steel nut which is pretty much guaranteed to rust weld it
making removal impossible.
When did they start this rip off?
I would guess with the TJ?
The YJ 258 uses screw studs and brass nuts as far as I have seen and I
have taken a couple apart. I sure didn't notice heads in there.
