Hobbit on Quest
The rules should do what logically follows from the fiction. Possible balance issues are another matter entirely.
Yes they should but lessons learned should apply as well. I'm guessing, from your line of comments in this thread, that you either didn't play a lot of 3rd edition or didn't pay much attention to the invisibility rules there if you did. But the nerf the invisibility spell got in 5e was pretty necessary compared to the 3e family (including Pathfinder). Invisibility has the potential to be extremely unbalancing - so it gets a lot of limitations compared to what you might assume could be true from the fiction.
