ifconfig uses plain ioctl's for that, it doesn't know anything about struct 
ifnet.  What suffers from changes like this are programs that use kmem(4) to 
access the ifnet list directly.  A grep turns up: routed(8), ifmcstat(8) and 
netstat(1), but there might be others.  A buildworld is best when in doubt.

To answer your concern, there should be no problem with ifconfig.
