-1. This would indeed be satisfying the wish for nice line labeling on tram
lines in the short term. However, implementing this one-time might encourage
others to just tag tram lines in this fashion and not even bother about the
relations. You know how these things go, as soon as you start doing this at
any serious scale, people will adapt it as best practice and we will end up
doing renderer-driven tagging, to which I am quite vehemently opposed.
Cross posting to talk.
