Verichrome Pan is not really sharp enough for 35mm. Plus they never made it on the new B&W film line. Plus-X they could certainly do a "special run" of, but they just can't sell enough to keep it in continuous availability. All the recent new Kodak films (Portra updates) were spinoffs from their motion picture R&D. Until recently motion picture film was about 80% of their business. That's the only business that could justify capital costs.
