We repeat "OSM is not a personal notebook" because this is not the first time this has happened, and certainly it won't be the last if we don't warn you about it. Better repeat it now, than waste time waiting for you to clarify potential future ambiguous notes.

We also need to repeat "link is link" because it is a fundamental principle on how links work, that you clearly don't fully understand yet. It's not even the extend motorway rule, not even highway continuity rule, just the definition of links (tangentially you can see that they are just corollaries!)

There is also no "reduction/redirection" to the motorway tagging topic, because motorway tagging is the sole topic of this note the whole time; the only disappointment here is your inability to understand that, and your reduction of anything you don't understand as a tagging mistake.

Yes, we can see that you do not agree with the extend motorway rule. Then, please discuss it elsewhere as mentioned above, e.g. relevant thread in Discord.
