Well, according to the first post, it's even more unsafe now, but somehow I doubt it. In the vids I see of Ragna getting his GH blocked, they don't really punish it. I could be wrong though.
EDIT: OK just saw Nu's 2B hit Ragna after GH was blocked, but it wasn't CH. Maybe the Ragna didn't block?
EDIT 2: OK just realised that if GH is unsafe on block, then Ragna's overhead options are complete shit. 6B was nerfed because of no C follow-ups, so damage off of 6B isn't good unless rapid. GH, while unsafe on block, has better follow-up options than 6B, but yeah unsafelol. BS is just BS. Slow-ass overhead that can be blocked really easily, and on normal hit cannot be followed up.
But that's OK, that means that Ragna is now the zoner character he was supposed to be
