The gear leg is probably not considered to be a "High Temp" operation despite the near proximity of potentially very hot brakes. I chose to use cotter pins on mine for that reason, but as Mark points out, he hasn't seen a problem with his either.
The one point I do want to make is that drilled bolts should only be used with castellated nuts and cotter pins or safety wire. The drilled hole creates a stress point in the bolt. I have seen a number of them fail for whatever reason when used incorrectly with self locking nuts. I don't care which way you do it, but pair the correct bolts with the correct nuts. As Sid correctly points out, the AC 43-13 (mechanic's Bible) says it's so, and it's for a very good reason.
