As an example: would it be preferable to add an alias with “駅” to all stations in Japan or add search support for every app and provider that uses OSM data?
Alias Pro:
Would be searchable everywhere without implementing it (helpful as it would help developing the apps without having to care about such search “problems”)
Alias Con:
It would add aliases for a lot of data that are in most cases just the name + some identifier or similar, which seems useless behind the fact you can get them all at once with a search “filter” in the providers.
Looking forward to hear your thoughts.
