From watching this video, my guess is 99.5 % of users won't be able to install this properly on their Switch Lite (and I include myself). They'll have to find a skilled tiny soldering guy somewhere to do the job for them, or buy a pre-modded console. Nintendo doesn't have to worry too much about large-scale piracy concerning this modchip, and shutting down the resellers is just playing it safe.
I can only agree - you have to find a soldering guy who is tiny, nothing can go wrong then.
