Oh yes, it is recommended in the wiki but that is only the first step talking about bike charging stations. It does not make much difference if I start tagging with
amenity=bicycle_charging_station
or
amenity=charging_station + bicycle=yes - designated - only
the task starts with the next step going into the details. Knowing that there are some CEE 7/3 sockets does not give me a clue if these are for bikes only (bring your own lock and adapter) or if there are some kind of bike lockers or even locker boxes where one can lock a battery or even another electronic device for charging. Just have a look at the sample pics I posted in #9. That is what we should have a comprehensive and consistent tagging scheme for.
And this is only for car chargers according to my knowledge. It was at least in 2021 when I posted a summary about the then acutal EU labels.
