'state' does not inherit display format or units from 'entity'

[ChrisJ60]

Linking a custom template row to an entity is useful for a number of reasons, one being the inheritance of a set of properties, one of which is state (i.e. the entitiy's value). However it seems the only the value is inherited and not the display format (number of digits, precision) or the units so the inheritance of state is much less useful than it would otherwise be as one always has to anyway format the value and add the units.

Could this be enhanced so that if one does not override state you get the same display as for a normal entity row?
