Cool! But, what about JWST? I mean, that's going to be so much better than Hubble, why not just give more funding to that?
On the other hand, It'll be cool to have Hubble continuing its mission.
Although, after reading the article, I do think that a backup would be good, considering if something breaks on JWST, we likely won't be able to repair it.
And hey! Dream Chaser has a potential mission!
