[Tagging] highway=residential_link

[Michał Brzozowski]

To me residential_link doesn't provide any meaningful distinction to
warrant a new highway tag. Maybe you misunderstood what link is about.
Links are for when collision-less means of joining or leaving high(er)
speed traffic are needed. From what I know about your residential_link
examples it's not really that, they are just shortcuts to make turns
less awkward. It's not standardized for a reason - they don't make
sense.
