I type a big long response and lost it.

Unless something changed recently, it may be that only some of them rx it.

It seems the old-timers who've been around since the CRAB trial era are the one's that are ok with rxing it. I got the impression that they don't have much faith in the options available to us ...

Unfortunately they are also rxing it to those on the interferons, so maybe they've had some not so great results and decided to stop. I don't know.
