I suppose the key question is: Does it identify the device and then decide not to work with non-Dell devices? It's fine to read required information, but unnecessarily constraining what happens based on that information brings it back to DRM.
It's not an open standard so this isn't really meaningful. The data has to be formatted a specific way, the Dell way that is, but it's not signed or anything.
The charger is just letting the load side know what it can supply... There are tons of cheap charges that are specified to supply 65 watts but will happily provide more than that until they melt or light the floor on fire..
