Last thing that was mentioned to the public afaik, is that Larian is hoping for a 2022 release, but might poke into 2023 as it seems now. Read that how you will, I personally have my mind set around the winter 2022/2023 part, roughly. But I don't mind waiting longer either, to me it's all the same, I just want a fun adventure in the end of the day ^^
Right. That would be approximately in line with the information presented on YouTube. It's fine, no rush. The most important is to have a good adventure and as smooth and bug-free game as possible.
I have no direct experience with modding, but I know as second hand information that a lot of people in the modding community for DOS 2 had problems with how limited and unintuitive to use the tools that Larian offered felt to them.
I’ve also read several complaints about how apparently inadequate for the job the “DM mode” was according to most of them.
If it’s a matter of unreasonable expectations rather than actual problems I wouldn’t know.
I play around with DOS2 editor and it's not bad actually. Don't get me wrong, it's not ideal.

People say they have a "love/hate relationship" with DOS2 editor.

I mean it looks good, all that. If you want to create a small adventure or a mod, which is add-in, the editor is perfectly fine. But if you want more, then... well... you need patience.

For whatever reason you often need to reload the editor for stuff to work. Osiris is not intuitive, but it's ok. Once you get hold of a syntax, you can work with it.
Actually I wonder why DOS2 editor is not that popular. It should be. You have the wiki all that, but usualy there is much more resources available on YouTube. Not sure why more people don't use DOS2 editor.
I am still using GateKeeper/ShadowKeeper/EEKeeper and DLTCEP while I play the original BG I & II series, waiting for the full release of BG III. It is fun to make new stuff ... but I don't want to be doing this for another two years.
If Larian doesn't want to issue an editor, just release the info the community. Get the game out!
Patience...

You don't want to do this for another 2 years??

DOS1 editor came 10 years ago. DOS2 editor came 4 years ago. BG3 will still be in production for at least another year.
I'm sure they have a solid roadmap of BG3 tasks and they will release BG3 when the time comes. In the mean time, you have EA to play around with. Patience....

I don't mind waiting for a year, but I'd love Larian to release any kind of editor at least similar to DOS2 one. But... ok, it seems we can still do a lot without the editor, so that's fine.
