I agree, anyone who's seriously looking to make an Emira their track car isn't going to want to start with an FE. They'll want an i4 base model and go from there. The other issue though, is getting one. Unless the parts and supply issue begins to improve, it may be harder to get one of these than we realize. With a hefty backlog of orders already on the books, it's not hard to imagine that growing quickly once the base model configurator comes online.
As far as track days, for the people I've hung out with and talked to at the events, there was quite a variety, from the guys who wanted to go as fast as possible, to the ones who just liked being out there driving on the track. Some would come in off the track and immediately go to the meeting center to see the times being posted. Others would just stand around their cars and talk with other enthusiasts; lap times weren't a big deal for them. They were into the cars, tires, brakes, etc. more than max speed.
I was always concentrating on improving my times; especially my entry and exits on corners. It wasn't the main reason I went, but I used that as a way to gauge if I was improving my techniques or not. I just wanted to be smooth, consistent, and quick. And I love the sound and feeling of just being there. It's a total focus activity; I don't think of anything else when I'm on the track. Unfortunately I've gotten to the age where it's just not doable anymore, plus there isn't a road course anywhere close to where I live anyways. I'm looking forward to the Emira as a reasonable fun car; not a max performance car. I can enjoy steering and handling without having to be close to 10/10ths. I want to enjoy driving it through the beautiful mountain roads of the Pacific Northwest, and take it on a trip or two.
