I dont think its an overestimation to say that later Britons regarded Constantine with respect and liking but in this regard there would have to be some analysis given to tribal>region.
I would be more confident of the universality of the civitas argument if we had a massive library of British latin text ala Gildas. (and Gildas is critical of Rome as he is critical of Britons). Of course there could have been a library destroyed by Saxons (but no mention) and we know libraries were destroyed various times in history, but regardless, the lack of substantial 5th century Roman military artefacts would imply the gloss of an administration rather than the creation of a strong Roman state.
