Certainly. Note I never said that the internal .so can't be in core
that both extensions interface with and perhaps wrap. It would be
nice to have a intra-extension call system worked out but that in no
way plays to the bigger issues at stake. This is all about management
of the public API; take a good skeptical look at the history of types
like xml, json, geo, money and others.
