> what exactly are the implications of enabling MPLS on an interface....

It normally means the interface can *potentially* be used to push/pop/
swap MPLS labels, ie. facing another P or PE router.

Absolutely not.

An MPLS enabled interface will normally handle a mix of labeled and
unlabeled packets. Incoming unlabeled packets can be regular IP traffic
(routing, Internet in a global routing table, etc) and various other
types (e.g. Cisco CDP).
