Define usage of interfaces without body

[PauliusMacernis]

Does it make any sense to have an empty interface (I mean, without any methods defined)?

In my current point of view - empty interfaces do not make sense because these tells nothing about the usage and most likely link to a wrong code architecture after all. If this is not the case of a wrong architecture then chances are very high such cases are linking to premature optimization which is considered a bad practice anyways.

Consider adding the rule that there should not be any empty interfaces, nor other type of abstractions inside the code base.
