You have me beat by 8 years, but I cannot think of a single company
that would worry about previous experience with an OS to chose an OS.
It is trivial to learn a new embedded OS and if I had an engineer
under me that couldn't do it, I'd fire him on the spot for gross
incompetence to be really blunt about it, at least in this job
market.

All of the companies I have worked for, except Microsoft (for obvious
reasons), would switch embedded OSes on the fly as needed or
dictated or needed depending on who made the decision to switch,
engineering or management and it was simply expected the engineering
team could adapt.  The APIs between most embedded OSes are nearly
identical.
