@futurebird NASA have taken the potential of a giant lunar telescope at least seriously enough to run this study:

The 1 km+ diameter LCRT is for capturing large wavelength radio waves to study the early (pre-star formation) universe.
For exoplanet studies, though, you maybe need something a bit different. Articles like this one put interesting exoplanet observations in the infrared and visible range (where JWST and future missions like Roman, PLATO and ARIEL operate):

I'm not an astronomer, but have worked on a couple of exoplanet missions as a spacecraft engineer. Critical factors in those were extremely precise pointing requirements, and ability to catch a planet during transit in front of its star. I'd guess that need to point in exactly the right place at the right time could be trickier to meet from a lunar platform that's pointing into the sun for much of each month, than from a space observatory at L2.
