You are completely missing my point.

I am trying to point out that "u-turn right after junction" is not necessarily inappropriate, and instead is just a "legit u-turn that's exactly at this extreme angle". The problem with that changeset is that you seemingly pulled it out of your arse. And, I have already pointed out that I dispute the existence of the existing no u-turn relation.

It is also not natural or obligatory to block the "one edge away", as it effectively is the legal way to u-turn under the presence of a no u-turn sign. Cf. u-turning on a double white line by turning into a side street (where u-turning is permittied) and u-turning and turning back out .

Seeing you still fail to explain why it's "never" appropriate to u-turn after a junction and instead dismiss it as "trivial", everything you have just said (software/data side whatever) is meaningless.
