The bktr author has been gone from the project for several years, and the
code had been neglected for a while before that.  The PRs against it reflect
this (that's the only reason I know about this driver; I wound up resetting
the PR assignments).

So this isn't a case of someone not following the standards, this is just
plain old bitrot.  With bugmeister hat on, I'd be glad to see someone pick
up this driver and fix it.
