@grimalkina @mavnn Huh. Well, OK! Practical data beats theoretical concerns, so if it's helpful I shall grumble more quietly. (What, me, not grumble? Hah, as if :)
I suspect this is another facet of "everything everywhere is a mess, nothing is ever perfect including the definition of 'perfect', so you do what you can with what you have at hand."
Life. Just a never ending series of compromises, but beats the alternative.
