I tried out this approach, mostly to try to preserve
icalendar--add-diary-entry's current default behaviour of showing the
resulting diary buffer.  However, I was wrong about
icalendar-add-diary-entry being called directly; the icalendar entry
point Excorporate calls is icalendar-import-buffer.  So I think the
original patch is fine as-is, as long as Ulf is OK with the change to
icalendar--add-diary-entry's default behaviour, such that it does not
show the modified diary file's buffer (which some third party packages
might rely on).  To determine whether or not to apply the workarounds
I'll check the "arity" of diary-make-entry.

I'll write the change log and push the patch this evening unless I hear
otherwise.

Thanks,
Thomas
