Ah ... now I too see what you mean

I agree that - especially if you are old-school - items in game lack an "in character" description. I think the main issue would be whether you can come up with enough original "in charcater descriptions" to satisfy the large number of items that exist in the game world (there are like 5 or 6 supplement health potions, alone).
But yes, this is something that is "missing" and I would enjoy having ... Although it is going to be very other-mod unfriendly. If anyone adds a new item, or changes an existing item ... Your mod would not cope with that addition/change ... I would need to think how one might technically achieve what you want to achieve in a way that is useful to people who play with other mods ... (maybe by using keywords?)
Followers: And I see what you are driving at here too. More rounded out Followers would have been great. And it is possible to build very customised Followers. But the issue here is that Voice-Acting is a must (I am encountering this issue, with my own stuff, right now).
- Making a (unique) fully customised Follower would require a lot of dialogue - But it is technically achieveable (technically, quite easy, I believe)
- Customising the existing Followers would mean either replacing all of their dialogue (so the same job as above) or finding a Voice Actor who can very closely mimic the existing voice
So; yes, more detailed/customised Followers would be fantastic ... but would also be a large undertaking (there is a quite-famous MOD for Oblivion that was the creation of a "fully-fledged" Follower ... but I imagine it took a great deal of time and effort to accomplish).
(An interesting topic, and much food for thought
