How do these new hub dynamos perform in snow and slush? I'm thinking of that brown mollasses like crap that occurs when roads are salted but not plowed and said brown crap builds up quickly on anything sticking out of a bicycle. Does it build up on the hub dynamo too? Does it affect the performance of the dynamo/light? Does it corrode the dynamo or its inner parts? Does it put undue stress on the wire running from the dynamo to the light?

Run OK. They don't slip as rim dynamos do and they don't
stop in extreme cold like batteries. And yes they get
covered in salty muck just like your feet and everything else.

Salt water will find its way inside just about anything
eventually, for example this 'sealed' Nexus:

The Sanyo of the 1980s were terrible for that, not as
resistant as a Sturmey GH6. Most modern units, even cheaper
models, are better now.

Wiring isn't any different, some setups are easily snagged
but good planning avoids that. Contacts can be coated with
dielectric grease usually $1 at any auto parts store.
