I get your point, but I would like to point out two things:
1.- @mano-wii is an official developer part of the main development team of Blender, up to my knowledge he is officially working in Blender, it’s not just a contributor that offers his free time.(I can be wrong, but I see his weekly reports, and usually that’s an indicator that he is in the main team as a part or full time paid developer).
With that said, this means nothing more than that is why I’m asking about this, because some where in the official planning this was at some point planned or at least sketched, so would be good to know the status, since it’s a very useful modeling tool once it’s correctly done, but with no other idea behind, the status can be “for the time being this is not going to evolve”, good enough to know it, no problem with that.
2.- In general I don’t see grumpiness in the latest messages of the thread, if you go back to September 2020, when I created this thread, maybe you can find something, but this has a history of an existing patch that was working way better than the new one, but made by a contributor, and there were reasons to discard that patch, but the functionality was greatly reduced, so there was a bit of controversy, on the other hand what I see is a user that is waiting for this to improve and is asking about it after more than 2 years, but he asks for it with a bit of despair, but respectfully, there are without a doubt other threads where you can see a lot of grumpiness XD, but I think this is not the case
You can also see how my message of January 2021 remains unanswered, yet I’m not angry or grumpy for that, it’s like when you send a friendly reminder about something to a co-worker or a friend, it’s important but not urgent, however it could be something good to know.
I hope you understand my point here.
