I wrote a certs cred callback for the TLS Pool before looking at RFC 7250.
It simply requests the bidir certtype and delivers what is being asked.
Had it requested the client certtype, then it would have automatically
do what it needed to do. That is the one change that would have to be
made. But it's only going to show up everywhere when the bidir certtype
getter stops being linkable; then app developers must choose which to
use. And from that point on, yes the applications ought to be ready
for it, I'd say.
But that's breaking an API, and this is harsh. As I said, no really
convenient solutions. (Another being to have to provide an indicator
forever and ever.)
