Having tested your code, I agree that we should keep `C-h P' as-is, but
extend it with everything from the "** Code:" header and down in your
code.  (I guess that part could be collapsed by default in order to not
overwhelm a user with details?)  It would be great if one could also
collapse the "Commentary" section.  I would also give it a headline
"Description:" using the same font as "Status:".

We would also need to check that this works also for packages that are
not installed (they don't need to show the full documentation, I don't
think, but they should at least not be broken ;-).

Bonus points if we can also add a link to the relevant Info manual,
where there is one.

BTW, does this all really need to be based on Org-mode?  Perhaps one
could make it look more polished by rolling a custom solution here, and
I'm not exactly sure what using Org-mode buys us in this case.

Three more nits:
- I wouldn't show obsolete aliases.
- The autoload cookies should probably get a better representation than
  just being copied in.
- The doc strings should be passed to `substitute-command-keys' before
  display.
