What Dr. Cheb-Terrab has introduced is, without doubt, a great achievement in the obscure area of theoretical physics that is of interest to only a minuscule fraction of Maple users. In recent years much effort has been developed to topics of interest to that minuscule fraction, to the detriment of a major fraction of Maple users.
One should also bear in mind that the entire assortment of postulated "fundamental" particles is itself questionable, because some of these 'particles' lack observation or isolation. Much fuss in the esoteric world of those who work in this area of physics results from self-promotion for the purpose of diverting massive funding from projects that might make the world a better place in which to live, and this achievement is likely to embellish that diversion.
Let us hope that the next release of Maple takes account of the nature of the mathematical interests of the major fraction of users, instead of reflecting the devotion of time and effort in esoteric directions and pandering to the abstruse domain of a relative few.
