[Request] shorthand for --list-subs

[Reino17]

For convenience sake, is it possible to add a shorthand -S for --list-subs, just like -F, --list-formats?

[phihag]

But -s is not a subtitle selection! So the -f to -F analogy doesn't work here. In fact, that would make it easier to list subtitles than to actually download them.

Without a convincing user story, I don't see any reason why -S should be assigned to --list-subs. In fact, apart from occasional debugging, I don't see any reason why you should use --list-subs in the first place.
