Yeah there is a lot of push back for full API documentation. I get it, they want to move fast and not have to rebuild thier old CI tool. But being open source its going to stifle development in the long run. I almost started building my own front end for Lemmy a month ago when there was only Jerboa but I didn't like some of the decisions of the core devs and I didn't want an ongoing battle to keep a front end up to date when changes are made.
I'm very appreciative to the Lemmy devs and all the app builders but I'm also lazy and perfectionist when it comes to coding in my free time.
