The point of including the servicename - if not as part of a TYPE
parameter, then as some other parameter - is to make it easy to have a
unique property-and-parameter set for every line in the vCard. This is
to allow for signed vCards which strongly authenticate a particular
set of lines rather than the whole vCard, identifying each line by its
particular property-and-parameter set. At present, the only way in
common usage to do that is with the PREF parameter, and that's not
exactly the job that parameter was designed to do - eg, I may not
actually prefer my Twitter account to my Facebook page, I just want
different p&p strings.

Perhaps in addition to allowing the URL property to accept TYPE
parameters, a new parameter could be defined, such as SOCIALMEDIA,
which allows for a relatively freeform text string as its value, to do
the job. (I'm picking that suggested name to ease the transition from
the current practice of using an X-SOCIALMEDIA property.)

Thank you for your time,
