Most vendors offer automated updates these days.  Deployments which are
not updated are likely to have other issues besides interoperability
problems.  Protocol fixes still do not end up in deployment.

I think we should try to figure out the reason before we try to work
around it.  If we're unlucky, the workarounds are broken in a similar
way, and we gain very little because vendors and deployments which use
arguably more secure protocol versions are still punished by an
incompatible installation base.
