A lot of the comments including yours sound gatekeep-y to me but I have to say I kind of feel the same way.
Everyone who has come here and stuck around found their way through the jank and is joining an exclusive club of high-quality discussion. Like Linux, once you can get past the basics, you can customize your experience nearly limitlessly, but it takes effort, trial and error to get to something you like.
I think overall it’s not a bad suggestion, and yes Photon looks very sleek, and I have even contributed a language translation for it.
However, my main concern is: what would happen if the main dev loses interest and drops support of the interface? Lemmy backend may add a new feature that either breaks Photon, or Photon can’t make use of it until updated. If the development of this frontend could be more integrated with the Lemmy project team and funded, I would be less concerned.
