The independently defined original wild group is pro-p

Its actual finite wild coordinates are p-groups, locally constant and jointly faithful. Closed-product permanence for pro-p groups therefore applies to the SAME original wild subgroup in its inherited topology.

EtaleFundamentalGroups.Inertia.actualNormalizationWildGroup_hasPGroupOpenNormalBasis

Original wild inertia has a basis of open normal subgroups with finite p-group quotients in positive characteristic of the original base residue field.
