I think the concern about data consumers in general is far higher on this
tagging list, then among actual data consumers.

For example:  Any decent data consumer needs to process *both*:



*    phone=XXX             +*

*    contact:phone=XXX*
Else they're missing 100,000 data points.   So even if *phone* was
mechanically retagged to* contact:phone* (or the other way around) data
consumers would* not even notice.*

It's the 18 pages of tag soup from
http://taginfo.openstreetmap.com/search?q=phone that hides phone numbers
from data consumers, not a potential well discussed and documented
improvement to the tagging architecture.

In fact worst case is not all that bad with a mechanical retag process:
if a data consumer breaks, it's because they're years out of date on
following evolving tag preference.

----------------------------------------

The access tags, and contact tags are both large tag spaces created before
namespaces.
If invented today, they'd problably use namespaces.
There are strong advantages for data processing, to have them groupable.
