I think this is an important point - it kind of boils down to the
question if directed mapping has the same freedom to use "any tags you
like" as individual mappers have.

Note the draft in B2 already requires directed mappers to abide by the
good practice rules (http://wiki.openstreetmap.org/wiki/Good_practice)
which includes the requirement to "Document your custom-tags". That
means while directed mapping is allowed to use any tags including newly
invented ones they have to document them.
IMO it would be problematic to deny any mapper the freedom to create new
tags because that would on the other hand encourage incorrect use of
existing tags. Because we have the free form tagging in OSM our tags
are not designed to cover all possibilities so there is always the
possibility there is something for which no established tag exists
(there are other geodata models based on the idea that there is an
exhaustive list of attributes and everything is to get the attribute
that fits best - this is not the case for OSM).
