Handrail wird doppelt eingetragen

[OSMmapper]

Mir ist aufgefallen das bei Treppen welche bereits "handrail:right=yes" und/oder "handrail:left=yes" beinhalten,
zusätzlich jetzt noch der Tag "handrail=yes" eingefügt wird.

Denke dies ist ein Doppeleintrag ohne Mehrwert.

How to Reproduce
Suche eine Treppe, welche bereits "handrail:right=yes" und/oder "handrail:left=yes" beinhaltet.

Versions affected

I am going to answer in English because this is nothing specific to German or Germany.

Without additional value - maybe. But this is how the tag is defined in the wiki. handrail should always be set, handrail:*=* is described only to further define the value. We have that kind of namespaced tagging in many places in OSM. I'd additionally argue that data consumers build on, to a certain degree, that the data follows the documentation, so if data consumers check for handrails, they do not necessarily check also the handrail:left/right keys if handrail is not defined.

So, unlike cycleway, where the wiki recommends to only tag cycleway:left/right instead because it is more precise, for handrail it states that handrail:left/right defines the value more precisely.

But in any case, one thing that I reckon now is that if someone resurveying the steps and not finding any handrail, the app should also delete the handrail:* tags, so this is the minimum that I should do about this.

Also, in regards to the argument I brought forth 2 hours ago, it would be a good idea to bring up some numbers: How much % of steps with handrail are tagged only with handrail:* and not with handrail=yes? How about the other way round?
After all what is written in the wiki is not everything and sometimes the wiki is wrong.

[westnordost]

About 9% of all ways tagged with handrail are also tagged with handrail:left/right.

About 29% of all ways tagged with handrail:left/right are also tagged with handrail.

Ok since this is a not negligible amount of taggings that do not conform to the current wiki documentation, I changed it so that it doesn't ask for places with handrail:* anymore except in a resurvey (every 8 years)
