[License-review] ESA-PL Weak 2.3

Another question to Carsten Gerlach:

The “weak” ("reasonable" or "moderated" sounds better) copyleft ESA-PL_Weak
provides the right to (re-)distribute the Software and/or Modifications
under a compatible licence.
Annex A lists only two licences: the GNU GPL v2 and later and the CeCILL v2
or later.

Questions:
1. Why not the GNU/AGPL, knowing that the ESA-PL_Strong covers SaaS (point
3.4 which differs from tha ESA-PL_Weak)?
2. Why not the EUPL v1.2, which should be considered since ESA is "quasi" a
specific European Agency (even if some members differ), knowing that CeCILL
v2.1 is compatible with the EUPL (and the reciprocate)?
NB: in addition, the EUPL V1.2 authorises specific agreements concerning
applicable law and arbitration, where CeCILL refers to the French law only
and to the court of Paris

Kind regards,

P-E.
