[Tagging] [Key:phone] - Suggesting wiki page changing

[websites at posteo.de]

As a heavy user of the contact:*=* scheme I do not see an advantage to
mark it as deprecated.

At least not as long as we do not have a proper way to tag multiple
kinds of phone numbers and are dealing with non-sense like phone_2=*,
phone_3=* etc automatically generated by the iD editor.

One frequent use case I run into is the distinction of landline phone
numbers and mobile phone numbers. The latter can be tagged by using
contact:mobile=* which is also properly used by data users like OsmAnd.
In my eyes even contact:website=* is not necessarily illogical as many
websites provide means to get in contact with the POI.

All the best,
