While I agree with a lot of these points there are a few things that have to be considered as well.
1) Intersect is to be shipped as a Vanilla ORPG engine, meaning they want it to have very generic base features and a simple to understand interface in order to welcome new users as well as create a stable source base to work from, each one of those features means more bugs, more code clutter, and not every game will need/want those features, again adding unnecessary clutter.
2) Intersect is developed by 3 people. These 3 people also have school, jobs, social lives, ect. Not everything will be perfect and not everything will be implemented, I prefer to think of Intersect as more of a gift than a product, they don't have to put in this much work, and they aren't paid for it, so anything extra being added is 100% the good will of JC, Kibz, and Panda.
3) These are extremely easy edits that even I, someone with almost no programming skill could implement to some degree. The source is not far off, if you've followed for awhile you'll know development cycles between hiatus and massive development spikes sometimes resulting in up to 4 or 5 entire release updates in a month. Beta 5 is the last beta version before the source is released so we aren't far off at all. I'd much rather let them focus on making it stable than abundant. Those features are nice, yes but at the moment Intersect is completely incapable of hosting any game due to the sheer amount of bugs, server crashes ect which is what the team is focusing on now.
Don't lose hope though, JC often comes in clutch and adds little QoL changes for the forum members however I wouldn't look forward to it. Instead, for now, grow the base from which to build your game; mapping, design structure, lore, ect.
