SO14 package at 154C/W? Really?

So here I am, needing more than the usual 32V opamp. Chose ye olde 
MC33174 because it can take 44V but was surprised when I read that the 
usual SO14 package is only rated at 154C/W. Since I am burning 500mW 
that would become too toasty, ouch. Or I'll have to idle two amps each 
in there and double the number of chips.

So, is 500mW in a SO14 really too much? What do thee say?
