Honestly, a lot of requests have been added compared to the initial version, and it has become a bit complicated. Maintaining an extension at this level is not something every extension developer can handle. There are very few extension developers who could maintain this, aside from the core team and the FoF team.
Personally, I was considering making a few attempts before seeing the latest requests. However, I would like to state that I currently have no plans to develop this extension, and I may have caused a misunderstanding in this regard.
Considering the previous extension requests, I believe a commitment of $100β300 might be necessary. Once again, I want to emphasize that I am not saying this for myself.
