I agree with John that this is the operational norm for WG5 and making an exception here weakens the norm for other proposals. 

An additional motivation for a TS is to provide purchase agents with a document to cite in writing a proposal that has the effect of forcing vendors to implement this, independent of whether it will ever be part of the base standard. Even if only one entity is interested in the feature, if its budget is sufficient it has the effect of forcing all vendors.  Avoiding this situation is a high priority.  The implementation costs greatly outweigh the benefit in this case, and vendors are not awash with free resources for such a project.
