You lack imagination ;)

You can assume in CLI just like you're assuming in GUI
Also you're consumming very precious desktop and home estate with your
stuff, you bet it will be central to apps.

When the user launches an app that needs one of your special folders, and
if it's not already registered (via symlinks or conf files), you propose
to create it.

Advantages :
- the user is doing stuff related to this dir, you'll have this attention
- you can explain what the folder will be used for, he won't be surprised
when other apps use it
- you can propose a standard name
- he can correct it if the translation is wrong for his locale, he already
has a directory for this use, or he thinks your default choice is stupid
for any other reason (that will happen more often than you think)

Contrast it with pre-creation of folders that may fit or not with the user
habits, may use the right locale or not, may be properly translated or
not, may be used by the user or not (some users will never do music or
pictures), may duplicate existing folders or not, etc etc

Sometimes asking the user is the right thing (as long as you keep light

That's a poor argument. No need to waste fedora-devel time if your choices
are set in stone
