Although for my day job I represent a specific hardware vendor, from a
services standpoint we will weploy multi vendor if it's the right tool for
the job.  What we do is try to limit the number of ad hoc differences.  So
I'd definitely be in support with the idea of using the 3.4 or 10 as a pure
bridge. That way most of the skill/knowledge for the hard bits (ie layer 3)
is still microtik centric.
