Hubble has served more than well and is now quite an old piece of hardware. Again space is an unforgiving environment, even for machines, and sometimes you have to replace the hardware. How amazing it is that they managed to get it back online, it is now operating well-beyond its intended design life.
I really hope that JWST will live up to its promises, I prefer they take their time and make every possible check before they launch that very complex and costly machine in space. I'm confident Ariane 5 will do the job.
If it is launched in last 2021 or even early 2022, I say fine, the timing is good. Of course it will probably take a couple of months to have it all set up, tested and fully operational, but that's OK.
