Scripts and triggers aren't part of the current repodata info but
*could* added to the "other" stuff along with changelogs where they wont
slow down typical depsolving activities. Pretty much everything else is,
and will be possible to query through repoquery, and some things which
haven't been possible will be, along with your favorite --queryformat
tricks (at least the basic ones :) :

[pmatilai chip repoquery]$ ./repoquery.py -a --qf "%{name} %{summary}" |
head -5
xosview An X Window System utility for monitoring system resources.
pango System for layout and rendering of internationalized text.
gimp-devel GIMP plugin and extension development kit
fluxbox Fluxbox is a windowmanager that is based on Blackbox.
gnome-libs The main GNOME libraries.

The leafnode thing is a bit different, but what you're asking for is
already possible with the prototype/in-progress repoquery: the first is
direct dependencies on "openssl" package, the second is openssl and
everything it provides against all configured repositories:

[pmatilai chip repoquery]$ ./repoquery.py --whatrequires openssl|wc -l
21
[pmatilai chip repoquery]$ ./repoquery.py --whatrequires --resolve
openssl|wc -l
157
