Exactly, options and choice is all this needs.
But really, The point where cheaters would exist happens once your map actually gets players 
The lag is also largely a optimization thing, If you have 800 devices on your map or a bunch of items waiting for events to happen then ya you are going to have lag. Like throwing on a bunch of physics and thinking its just gonna be optimal. A lot of these parkour or tycoon maps are not remotely optimal so it would make sense they lag.
Also, Verse replication is really good and if we are to ever reach this goal tim etc have of 1000-100000-1000000 player servers this region lock has to go.
But really, we cannot be holy reliant on discovery because discovery is just going to make the best $ decisions forever so we need a way to take are niche maps and “craft” our own player base. The reward of that could be discovery sure once we prove ourselves but this is basically what a lot of the pillar talks epic does talks of “crafting” our experiences experience for example,
but what use is that in this system? with a lobby system that doesn’t support that we are all holy dependent on discovery and those talks don’t really mean much, were just begging for discovery, epic picks, or some form of insider special privilege cause otherwise we have nothing outside of marketing.
