On the equipment I've serviced (Rheem), the EAC requires heat and
blower in order to make power to the terminal. Terminal provides 110
volts, incidentally.

OK--but could I not just wire to EAC terminals and keep blower on
continuous?

You're stupid. The EAC terminals on the furnace control boards do NOT
need a call for heat and blower to power the terminals.
Blower only you dip.

Correct..

the HUM terminals or wire taps are only engaged when the gas valve is called
for

So disconnect the HSI and just the fan will run making your humidifier run
:o)

No offense but I already knew I was correct. :-)

.......and many of them (the hum terms) are powered as soon as there
is a call for heat and not just once the gas valve finally gets
energized.........but Im sure you already knew that too.

I'm still thinking it might not be such a good idea to run your
humifier without heat. That increases the chances of it condensing out
somewhere in your duct work. Not trying to start an argument or
anything but there are some real horror stories out there about mold in
ductwork. Once it starts you pretty much have to rip out everything to
really get rid of it.
