  In characterizing the yields and ratios various of well identified particles
in the ALICE experiment, we utilize extensive {\it additive} thermal
approaches, to which various missing states of the hadron resonances are taken
into consideration, as well. Despite some non-equilibrium conditions that are
slightly driving this statistical approach away from equilibrium, the
approaches are and remain additive and extensive. Besides van der Waals
repulsive interactions (assuming that the gas constituents are no longer
point-like, i.e. finite-volume corrections taken into consideration), finite
pion chemical potentials as well as perturbations to the light and strange
quark occupation factors are taken into account. When confronting our
calculations to the ALICE measurements, we conclude that the proposed
conditions for various aspects deriving the system out of equilibrium notably
improve the reproduction of the experimental results, i.e. improving the
statistical fits, especially the finite pion chemical potential. This points
out to the great role that the non-equilibrium pion production would play, and
the contributions that the hadron resonance missing states come up with, even
when the principles of statistical extensivity and additivity aren't violated.
These results seem to propose revising the conclusions propagated by most of
the field, that the produced particles quickly reach a state of local
equilibrium leading to a collective expansion often described by fluid
dynamics. This situation seems not remaining restrictively valid, at very large
collision energies.
