When called with this extra arg, mapcheck() could return a conflicting/ambiguous lhs (or list thereof) in some canonical format (possibly determined by the value of the extra arg itself). As long as the format returned could be fed to maparg(), it would be possible to find conflicting mappings, remove them temporarily, and subsequently restore them...

If you define a mapping you will want to know whether the mapping
already exists and needs to be restored. For that you can use maparg(),
no need to use mapcheck().

Not sure why you would want to remove "conflicting" mappings. Perhaps
when you map the ; key, and the user has ;x mapped? Then you would need
a list. Adding a maplist() function would be better than adding
arguments to mapcheck().
