Pretty sure the 2016 delay was for multiplayer. That was the year they said it wasn't planned to be released with the game, then they got massive backlash and shorty afterwards from the 2016 games-con the game was delayed till 2018/2019 then the release date was left blank, then we got beta in 2019 for multiplayer and now we have EA. Features get lost all the time, but on the other hand features that specifically said they wouldn't be in the EA on steam and in forums have actually ended up in EA like kingdom management screen, and the custom weapons. Additionally, there is no reason that they wouldn't have a list of features they are working on, but are not complete enough to run smoothly and so haven't been pushed to the latest build yet. Most of their focus has been for prepping for release the last 6 months and that pretty much came to working on multiplayer, ports, and probably smashing whatever they could out of the dev cycle into their latest publishable build.
A lot of people forget Warband was a particularly nasty piece of work on its release too, but got much better over a couple months including a complete rework of the combat animations, multiplayer overhauls and additions of features like feasts and stuff, and back then they had what? a studio of like 20 at most if IIRC. Furthermore for the longest time, they hadn't passed 50 people I think on Bannerlord's development for the first 4-5 years too IIRC. A lot of people like to use the size of a dev team as a complaint at launch, but its really not indicative of the average workforce over the development pipeline. I am not too worried about the missing features not coming in, because its in roughly the same state as Warband's release, but with way more development power behind it now at release.
