Should event detail pages' forms recognize (or handle) repeat submissions from the same visitors?

Today, the event freely lets the same visitor fill out the same form multiple times without any real indication that they're going to the same contact. Is that desired behavior?

If not, we could try to mimic some of the features HubSpot forms has (progressive fields, auto-fill), but I'm more curious to see how replacing our custom jsx form with a native form embed in its own component would feel and what the tradeoffs there would be.
