Things suggested within the thread are one time things with no repeat value and close to zero connection to the rest of the game. At best they have atmospheric value. If there was nothing to add or improve to the main mechanic of the game, I would have nothing against it. But there is plenty that can be added or improved in the game that would add way more playability value using the same resources.
Then I have a feeling you aren't really reading all of it. For example:
Yeah, I'd quite like to see that rebalanced a bit. Once you've made it to the stage being a landed noble with your own castle(s), I kind of feel like there should be less emphasis on constantly buzzing around the map like a blue-ass fly.
I'd like to be able to delegate the more mundane tasks like collecting food and recruiting soldiers to some minion, while I deal with higher political matters from inside my keep.
If you want to be continue constantly traveling around visiting villages and keeping the roads clear of bandits, then you absolutely should be able to. But you also should be able to tell Nizar (or whoever) to do that for you because you've spent the whole early game doing it and now you've earned yourself a break. Notables and Lords should come to you if they want something.
A change of focus and a change of pace when you become a landed Lord would also compliment the family/heir mechanics. Now you're in the ruling class, you're less focused on the day-to-day, but on higher matters of state and on the generation-to-generation progression of your family. Time speeds up as you take the longer term view. You take to the road now only for more important matters that require your personal attention - which by their nature are less frequent than when you were an independent adventurer. Visiting your king or other kings and lords. Leading your men to war.
So yeah, I'd like to see more focus on staying in your castle once you get to that stage. Not just for role playing or for creating 'immersive' distractions: for gameplay progression.
It feels out of place to do the same little tasks that you did when you were just a poor traveler when you've gained a fiefdom, even a kingdom. It should be possible to do them if someone really wants to, but it'd make the game progression not only more immersive but also more interesting if you had the option to delegate and use your castles or towns as places to actually do things now that you don't necessarily have to run around collecting food and whatnot. This concept of "doing things" doesn't necessarily have to be just simple cutscenes or minigames, could just as easily be things like telling your court to do things for you. Like ordering some of your companions to pick up a patrol and go deal with bandits that harrass the roads in your domain. Or ordering some peasant to go buy food and supplies when you are preparing to ride off to war. Or sending messengers to contact other lords so that you don't have to run around the map over and over again just to speak with someone.
There are plenty of things that could be interesting in terms of gameplay and immersion that aren't necessarily just one-time things.
All that being said, I still think they should prioritize the development and polishing of core features instead of adding anything new and potentially complex like this.
