'Don't think so. Hubble could have been easily used for disclosure too. No need for a different telescope'.
I think Hubble has captured extra-terrestrial craft and life - we would never be told of it publicly, and possibly the quality of imaging data is not optimal.
The ability of The Webb is extraordinary - yet its the instamatic model of what's to come.
The Hubble data is too close to Earth - whereas the The James Webb can put the disclosure so far away from us that it doesn't feel 'threatening'.
I think the 'disclosure crowd' would prefer curiosity first than chaos, from the public.
I think they need something prior to contact and hard evidence. They have been talking of a soft disclosure, something done in increments - and I think the telescope could/would do it to start the ball rolling - all they need to do is to report something credible enough to say 'we are not alone' - and its in a galaxy far, far away.
They have already predicted that within 5 years of launch, the telescope will find something.
Another interesting thing (possibly needs its own thread or added to a disclosure thread) was the recent report that NASA has been in conference with Theologians and Religious experts as to how to intergrade science and religion - the first meetings noted being held in 2008. The report is about the Stanford Uni research dates range from 2014 onwards.
The denominations might need a photo or two from the James Webb to help them along.

NASA 'looks to the heavens' for help: Agency enlisted 24 theologians to assess how the world would react to the discovery of alien life on distant planets and how it might change our perception of gods and creation
• NASA enlisted 24 theologians to take part in its program the Center for Theological Inquiry (CTI) at Princeton University
• The group assessed how humans will react if alien life is found on other planets and how the discovery will impact our ideas of gods and creation
• Dr Andrew Davison, a priest and theologian at the University of Cambridge with a doctorate in biochemistry from Oxford, is one of the theologians
• Davison believes we are getting closer to finding life on other planets
