That's entirely up to you.  Nowadays there is hardly any site that will
work without cookies (and javascript for that matter) enabled, but there
has been a push of late for people to disable cookies for privacy
reasons, so you may still have issues with it.  If you're concerned then
the old standard demo settings should suffice:
ScratchDefault  mv_no_session_id  1
(implicit): ScratchDefault  mv_no_session     0

With the above settings Interchange will only add an id to the URL if
the browser did not pass a MV_SESSION_ID cookie.

I think it's safe to get rid of the mv_pc alltogether.  Stock
catalog.cfg has had it thus for years and I haven't heard of any issues
with browsers caching old IC pages:
ScratchDefault  mv_no_count       1

This is a bad habit and should be fixed.  There are other very good
reasons to use the area tag other than just generation of mv_pc and id
attributes.  If you explicitly want a link without those attributes then
you should still use the area tag and pass no_session=1 to the tag.
