Oh well, so my question is:

is better to have a long list of options or just one -list elts?

I want to extend support for listing, for example have
-list pix_fmts
-list filters

I prefer the -list idea as I repeatedly stated, but then I could also
consider the other way (having one option for every list), please
express your opinion, otherwise I'll commit this after a week since
now.

Regards.
