Perhaps it could open the doors to near infrared imaging? Longer wavelengths are less scattered by interstellar dust and atmosphere, so adding effective near IR imaging to one's repertoire could be quite interesting
Also, could simultaneous collection of a wider range of wavelengths help with Galaxy imaging? Bringing a wider range of wavelengths to a focus would certainly challenge refracting telescopes, but reflectors would be perfect for the task.
If one day sensors will commonly become sensitive to a wider EM spectrum, perhaps there will be time when refractors will become less useful for amateur astro-photographers and reflectors will dominate in the field of amateur astro-imaging...
