When there is limited time/resources to implement new features, a work around is probably the solution you are going to be offered. I don't believe the administration has a lot of people working on coding new features.
Admin, theymos, is the only person who codes the forum, this one, and Epochtalk (new forum software). As theymos said, he is more familiar with the forum, after years, and he has not yet really wanted to move our forum to Epochtalk due to some risks when making data transitions.
None of these ideas are new to me. Even if I don't respond to suggestions, I do read them, and they float around in my mind going forward. If it's not already done, then there's some reason why. A big possible reason is that I'm the only person who does development on the current code, and my time is limited. Another big reason is that this is a huge forum with complex dynamics, and even small policy changes can have big effects which need to be thought through very carefully.
I started the topic because I saw lots of people think that they have to click on Preview button to save their posts in Draft page. Then, I discovered theymos announcement about Draft page long time ago, that clearly states that users don't have to do this, clicking on Preview button is just one of triggers for Draft page.
