It's just really cool sci-fi tech that I want to see used in something other than DLP chips!

JWST and other observatories with segmented primary mirrors kind of use the segment alignment one time to get the correct alignment once. Then there is Adaptive Optics. It's kind of the opposite direction though as they are using a laser to detect the distortion so it can be compensated in the image. From learning about SDI when I was a kid/teen, it's just always been about controlling the laser itself in my mind.

The JWST does not have to deal with atmosphere or weather and uses a giant sun shield to keep the internal temperature stable so these alignments have the longevity you need to make the platform work.
