I am not saying that I am working that way, but other people may.
We need to remember that often Scribus is used by inexperienced users, so why there may be better ways to do things, inexperienced users tend to not always do things the best way:)
I think it is important to try to help inexperienced users while at the same time not disturbing experienced users.
I know a lot of people who never bother with file names, instead they use preview to find the right file (no matter if it is a Word document or an image).
Personally I am picky with file names, but that is mainly because I am so used to using Total Commander as a file manager.
For example at work our quality department has made folders:
Internal audits
External audits
among dozens of other folders.
I would have named them:
Audits - external
Audits - internal
