This could be described as a bug rather than a feature request.

We hosted a 'pop-up rave' style event, where we only wanted to divulge the location of the event the day before. This was mostly to protect the teams setting up the event from snoops and offer some kind of mystery to the occasion..

When setting up the event in Hi.Events, we were forced to either specify it as an 'online event' or pick an address, both which would have been confusing to attendees.

Oddly, an event defaults to being in person, but with no address is specified, but if you change the address setting in any way, you are then forced to fully fill out the address fields.
