This isn't anything new really, Sony makes different versions of the first console which can make you feel like you should have just waited or your glad you bought one before this. I think Microsoft makes different versions of the Xbox as well and at least with Playstation they are upgrading ALL Ps4s to HDR ( Which IMO sounds better than 4K to me), so all you will need is a HDR tv. I don't think it's hurting the community, if you have some extra money and/or really care about all the stuff the Pro is offering then get it, but if you don't then don't. Since HDR is coming to the current ps4's, I feel I can hold off on getting one without feeling to left out, but I most likely will get one around the Ps5 or something. Plus, for what they are offering, the Pro isn't that expensive (I don't know how much the scorpio is).
I'm with you on this. This isn't anything worth getting worked up over. 60 fps isn't a bad standard to look up to, if anything I feel that it's amazing that we've advanced so far in the world of gaming that we can even worry about fps as the next hurdle to jump over. It's just another link in the chain that is progress. And besides, they made it explicitly clear that regular PS4 users are not going to have an obsolete experience, the Pro is just an alternative for gamers who have the extra time, money, and interest in getting something that delux. This is just giving you more options rather than making one super-console that you either have or don't have, this way no one gets left out. If you have the means to buy and enjoy it, then get it, good for you, but if you don't then don't sweat over it, you'll still get an awesome experience with the PS4 and the HDR upgrade that's coming, you're still getting an enhanced experience either way.
And seriously, console add-ons are nothing new, we've been "rewarding" game companies like Nintendo, Sega, and Sony for releasing multiple versions of the same console for years (I mean the Sega Genesis/CD/32X anyone?). It's not a new trend that needs to be stamped out, it's just an already existing part of the cycle that we just accept for the most part.
