My previous comment is a standard response as member of the Hungary Community in case of reporting missing map features. See our wiki page: https://wiki.openstreetmap.org/wiki/Hungary/T%C3%A9rk%C3%A9pjegyzetek-Bejelent%C3%A9sek

My personal opinion is same. This note is quite old and not resolved for a long time. It does not provide enough information for a map editor to add it to the map or fix it in the map (in contrast of mentioned street name, address, which can be added/fixed by editing). We are working hard on the improvement of the map, but our resources are limited. We are very welcomed your help for the adding of the missing map features. If you want, you can decide to add memorial indicating the source of information (optionally tagging with fixme=resurvey if unsure). Map notes are not for marking probably existing items, otherwise without awareness their count increases to an unmanageable amount.
