IIRC correctly they also wanted a halo for the JWST that would keep a
minimum angular separation between earth and sun. I guess it's not good
to point your communication dish in a near sunward direction.

The usual problem is not damage to the hardware -- even if you're using a
solid dish rather than a mesh one, problems with focusing of sunlight can
be limited by choosing a suitable paint -- but added noise in the
receivers from having the Sun in the background.
