It's only good for 5.5V absolute maximum supply voltage, which might be
a problem on 30V (+/- 15V).

The requirement for high voltage operation *and* R-R operation is quite
rare, in fact I suggest it might be an error to add that constraint. Usually
when you have +/-15V supplies your signals are limited to 10 or 12V.

If it's two separate applications, then two separate part numbers are
probably called for, rather than trying to find one magic op-amp that
can do it all.
