The documentation you linked to describes how to provide
information_schema plugins but not why you would want to do such a
thing. I'm not seeing why this would be useful. The information_schema
schema is described by the standard so creating new views in it isn't
needed very often and the schema for the existing views doesn't change
very often. I can see why a plugin might want to add rows to the views
but that doesn't seem to be what this feature is about.
