It was the early days of homebrew when there wasn't much information out there and the tools were much less advanced. I didn't really care about the risk either, so it could've been anything. I wasn't immediately banned either. Took about half a year or so.
But yeah, emulation can pretty run all the relevant titles, meaning the exclusives, much better than the Switch itself.
That sound's like the data is in semi-regular use at least. For me it's more like "Do I seriously need the sequel installed for that other game I haven't even started yet, but am definitely going to start any day now, after years of having it installed?".
