Speaking as a minor-mode author, I would expect Emacs to provide a
default that handles the known cases in a reasonable manner, the known
cases IMHO being those I described. If someday someone comes up with a
use for the margins that cannot be handled properly, it makes sense to
allow the default to be overridden.

If the value of `set-window-margins-function' is a single function, then
probably the function provided by the last mode to be activated in a
buffer.
Isn't that a potential problem?
