Too many package level constants/variables?

In my opinion, layers package is too polluted with exported constants/variables. Would it be a good idea to have separate package for each layer?
Perhaps all commonly used layers in a single package (_layers_), and all uncommon layers in their own packages? (e.g. _layers/lldp_ package).

This can have an additional advantage of shorter identifier names because then we can drop prefix. For example, _layers.LLDPChassisIDSubType_ will become _lldp.ChassisIDSubType_.

This would be breaking change however.

Any thoughts?
