  S. Brodsky, F.J. Llanes-Estrada, and A. Szczepaniak formulated the $J=0$
fixed pole universality hypothesis for (deeply) virtual Compton scattering. We
show that in the Bjorken limit this hypothesis is equivalent to the validity of
the inverse moment sum rule for the $D$-term form factor. However, any
supplementary $D$-term added to a generalized parton distribution (GPD) results
in an additional $J=0$ fixed pole contribution that violates universality.
Unfortunately, one can not provide any reliable theoretical argument excluding
the existence of such supplementary $D$-term. Moreover, the violation of $J=0$
fixed pole universality was revealed in field theoretical GPD models.
Therefore, $J=0$ fixed pole universality hypothesis remains just an external
assumption and probably will never be proven theoretically.
