I don't say here, 'rendered in OSM-Carto', I say 'rendered somewhere'. I'm entirely willing to do my own custom rendering for objects of special interest. But, when I've asked questions of the form, "how can I most effectively tag objects of type A from objects of type B, because I wish to render them differently on my own maps?" (Example: the access=permit kerfuffle), I've repeatedly been met with an argument that I'm tagging for the renderer. It is not 'tagging for the renderer' to make the observation that no conceivable renderer can make a decision based on data that are not on the map! The discussion of indefinite objects falls in the same category in my mind. We shouldn't have to discard what is known or defined about an object because some other part of the object is unknown or indefinite. We can't map what is known if we've thrown it away. I don't want to throw away St. Lawrence County because nobody has ever surveyed a line through the swamps of the St. Regis basin, and I likewise don't want to throw away Jamaica Bay (or for that matter, the Gulf or Bothnia) because we don't have a 100% agreed-on field-verifiable bright line across their mouths. I recognize that the Gulf of Bothnia may fall afoul of technological limitations, and I've conceded that point, but in cases where we won't cause widespread breakage, it surely makes sense to do what can be done with the imperfect information at our disposal!
