Are Complainants Abandoning TBT Agreement Article 2.2?

This is from a paper about WTO dispute settlement published on the ICTSD website as part of the E15 process:

there is evidence that the existing ... perception that claims under Article 2.2 of the Agreement on Technical Barriers to Trade (TBT Agreement) are extremely difficult to win is having a deterrent effect on potential complainants pondering whether to bring claims under this provision.

What happens if governments stop bringing Article 2.2 claims?  Is that a problem?  Or is that a solution?
