These threads are always kind of ironic, since casuals legitimately seem to think the majority hate wild encounters as much as they do and simply don't care about the impact of taking it out, as long as it is. While I am an outlier with little interest in non-RPGs that only runs from wild encounters when I have no other choice, which is to say almost never. Most people on the other hand are amicable with the formula and delegate as necessary. People that hate wild encounters are extremist in their view of the mechanic just the same way I love them.
Fundamentally, though, as much as you might hate wild encounters, replacing it with a worse alternative doesn't solve anything. This sort of mechanic has been tried before and all that it does is undermine depth, making the game a much more shallow experience and Go is the perfect example of the future of such shallow games, it had its 15 minutes and earned a lot with that popularity, but it's dead now and the party is over. Meanwhile, the series has gone steadily for 20 years earning the same sort of revenue consistently that Go managed in just the short amount of time it was popular.
Ultimately, LGPE's fate is already sealed, too. Go died because casuals were alienated with more recent Pokemon and no gameplay, and as they bailed mobile players bailed. LGPE's potential success, assuming it's even able to overcome the whole hardware issue and the mobile users never crossing over, it can only reach yet another impasse: if genwunners in practice hate 'newer' pokemon so much that they blew out because of it, since LGPE has newer pokemon (and even an unannounced pokemon waiting to be revealed no less) it's going to lose its momentum quickly and that popularity will not continue into what is quite likely an already planned follow-up.
And like others have said, because these are such shallow games, even moreso than what we've seen in gens 6-7, the core fans literally aren't going to give a fuck.
