Mismatch loss should not be included in "antenna gain". Matching is a
separable problem. I think most engineers take this view. It also
makes sense (to me) in terms of partitioning a system into manageable
pieces. I'm not denying that some antennas that have good gain may be
difficult to match, and that often gain can be traded for matching.

Similarly, and with no intention to minimize the importance of
polarization mismatch in a link budget, polarization mismatch should
be called out separately. Again, this is what I'm accustomed to
seeing in specifications and budgets.

Yes. Isn't this standard practice? Why do you ask?
