This irks me enormously. It is the direct outcome of the cambium
elevate lawsuit, where both companies lost, the ISPs lost, open source
practices long established about publishing sources, lost, and the
lawyers went on to other nasty things leaving this trail of awful

I do not know what to do about it. It also irks me that as a
contributor to "smart queues" they are not maintaining it well.
