I assume that these digitised PRoW Maps from local councils are released under the OS OpenData License. That being the case, please note that Ordnance Survey have recently stated that their "OS OpenData licence is not forward compatible with the ODC-By and ODbL" [1]. Hence these datasets cannot currently be used as direct sources for contributing to OSM.
I absolutely agree that the paths from these maps cannot be imported into OSM with the current licensing. This is clear. However, it would be great if we could use them just to add the "designation=public_footpath" tags to paths that have already been surveyed. Do people think it would be acceptable to, for example, view a paper definitive map at the local council office, and then update the designation tags manually? If that's allowed, surely it is possible to construct an argument that an automated equivalent process using the digital versions of the maps is allowed. Is it possible to claim that while the geometry of the path is derived from the OS, the fact of it being a public footpath is something added by the local authority; if OSM substitutes its own path geometry, the OS intellectual property is removed. Ideally, the local authority would then disclaim any rights (or adopt the plain OGL) over the remaining data: after all, they are only using the OS licence because of the OS- derived elements. Hmmm, that's not too convincing. Maybe someone else can come up with a better argument.
