Having said all that, I'm now leaning toward not putting the interface name PTR on the IPs of boot interfaces, since that seems to be the more general mode.
Note however: if multiple names resolve to the same IP, then all of them will be in the PTR RRset. (Since this is a valid and often service-required state.)
