(only commenting on the uncaching-related part of this; I haven't read
up on the rest of this discussion yet, and haven't looked at the recent
code.)

If the behavior is changed from "only reload top document after
relevant option change" to "reload all affected documents after option
change", then please make this optional/configurable.  The current
behavior is maybe sometimes unexpected, but I generally prefer it over
the alternative.  I know where the ^R key is if I need it, and would
like to avoid unnecessary reloading.
