From our discussion, we think it ought to be something like:
if (util.dimensionless_contents(self.streams, self.kdims)
raise KeyError('Using dimensionless streams disables DynamicMap cache')
elif self._disable_cache_lookup:
raise KeyError('Cache lookup disabled')
That way the variable isn't about streams and you can disable cache lookup on dynamic maps not matter how they are (or aren't) using streams.

I think we decided in the end that it is about streams.

Currently the plotting code will request a particular key from a single DynamicMap multiple times during plotting which should be avoided due to potentially random state.
