It sounds nice to do that, but look at it from a dev perspective:
You have all this hype for your game, you've had to juggle working on your game with other commitments including irl events or relationships. You know you dont want to disappoint your players, but at the same time you want to release it just as much as they want it. You avoid release dates because they only serve to break hearts, be they unfixed bugs that would have been fixed had it been later, or unfinished features/locales, or even overshooting it and releasing it months after the posted date because something kept going wrong during development.
With just as much hype for SpaceEngine 0.990, do you really want to risk upsetting the vast majority of your playerbase with an underwhelming or broken feature?
As a modder myself, I can already kind of relate to this, even if I dont get much actual attention. For example, that ocean mod I posted earlier? I expected it to be done within a few hours. Rookie mistake, obviously. Took me 24 cumulative hours to get it done. And trust me, that includes one 3 hour stretch of profanity towards my helpless laptop who didnt deserve this.
But ja. I look forward to release day too.
