I think so, since if a package sets it to t, and user has
`highlight-nonselected-windows' it would upset the user.  A different
solution would be to introduce a new variable that mirrors
`mark-active'. But that would make `mark-active' redundant w.r.t. that
variable.

I will try to make the mark and `mark-active' window-local instead of
just `buffer-local'. In that case, it will still be fine to have
`mark-active' set to t. I don't yet know how hard this task would be.
