Note that

+       (with-selected-window w
+         (when (functionp window-set-context-function)

and

+           (with-selected-window w
+             (when-let ((context (window-parameter w 'context)))

would set up a precedence case for the future use of
'window-set-context-function'.  Are you sure that you always want to
select the window in question here or would it suffice to pass the
window as argument to the context function?
