One of my favorite things in scifi is when later movies/shows have to try to write around old design chocies.

Both have honestly existed for a long while. The term is hard SciFi and soft SciFi.

Hard SciFi is concerned with making sure that it's rules are self consistent and the ramifications are clear. Early examples include Perry Rhodan, which had schematics for technologies in the story on the silver books.

Soft SciFi however is not concerned with those issues, it wants to tell some specific story but if the FTL they used has consistent and realistic rules is not that important.
