I understand your frustration and hopes to see our ecosystem become feature complete as soon as possible. I'm just afraid about your expectations.
There are only a handful of developers who regularly build extensions for free. Of those, only a limited few actually do so based on feature requests. With the number of feature requests going on, I don't think it's fair to assume that this particular one should get priority.
Understand that building extensions doesn't stop with just building them, the aftercare is a large drain on the developer time and - even more so - motivation of the developer. Once you spend more time on maintenance than building awesome, enjoyable new things, you slowly near the developer fatigue stage with a risk to burnout.
Let's protect our ecosystem, our extension developers by valuing their time. Don't pressure to get your features build and if you can, support them.
