Double-sleeving

Is double-sleeving a 1.5'' pipe for GBs absolutely nessacary? Wiki said unsleeved GB barrells are too brittle..is this true?
Normal 1.5" (sch 40) pipe has a wall thickness of .19"; 1.5" sdr-21 has a wall thickness of .1".
This does make it weaker, although (especially with short barrels), it's not actually necessary to sleeve it... although it is a good idea.
