Thanks, Paul and Mengxin Zhu!
With your help I was able come up with the following two queries to separately
list feature groups and plugins which respectively include or require a given
p2 IU.
everything.select(iu | iu.properties['org.eclipse.equinox.p2.type.group']==true
&& iu.requirements.exists(rc | everything.exists(x |
x.id=='org.eclipse.emf.ecore' && x ~= rc)))
everything.select(iu |
iu.properties['org.eclipse.equinox.p2.bundle.localization']=='plugin' &&
iu.requirements.exists(rc | everything.exists(x | x.id=='org.eclipse.emf.ecore'
&& x ~= rc)))
Furthermore, it is possible to make them run much faster if
org.eclipse.emf.ecore is only sought once, e.g.
everything.select(everything.latest(x | x.id=='org.eclipse.emf.ecore').first(y
| true), _, {req, iu | iu.properties['org.eclipse.equinox.p2.type.group']==true
&& iu.requirements.exists(rc | req ~= rc)})
everything.select(everything.latest(x | x.id=='org.eclipse.emf.ecore').first(y
| true), _, {req, iu
|iu.properties['org.eclipse.equinox.p2.bundle.localization']=='plugin' &&
iu.requirements.exists(rc | req ~= rc)})
I'm happy now!

Subject: Re: [p2-dev] Querying p2 for a list of reverse requirements
IU 'Tooling.xx' is a kind of config IU, which takes responsible to update
eclipse.ini, set start level and etc. They have requirements to match any
bundle, what's why they are queried.
Try below line to exclude config IUs and feature groups,
provlpquery this "everything.select(iu | iu.providedCapabilities.exists(p |
p.namespace == 'osgi.bundle') && iu.requirements.exists(rc |
everything.exists(x | x.id=='org.eclipse.emf.ecore' && x ~= rc)))" true

AFAIK the all of the IUs that start with tooling can be ignored3 (they're
generated by PDE build, although their purpose escapes me at the moment). If
you remove them, then your list is more reasonable.
