A table listing modules and themes and their key properties. Also offers json and yaml as alternative output formats.

Needs review.

Is there a reason to not list profiles and database drivers too?

Themes and modules are the most common obviously.

A few questions and comments.

I could be convinced profile and database drivers should be a follow up, but I think it's probably not too much to include here.

Thanks for putting this together!

Moshe mentioned in slack that Drush doesn't support listing database drivers or profiles and has never had a request for it.

I think profiles might be useful, but it can be a follow up.

As for pm:info I created #3605796: Discuss creating a pm:info command

There is a CR, not sure if we want more detail on the options, but I think it's good.

Still need to manually test the options.

Ok I manually tested:
type for both options.
format for both options.
core
installed
and I tested package with Core and changed a module to use a test package and confirmed it works as well.
