Cloudflare as registrar, good or bad idea?

Gandi are jacking prices up again so I'm moving. Previously had Gandi as a registrar and another service as the actual nameserver, but Cloudflare don't allow this. I was intending to move NS to cloudflare anway, so it's not a problem technically, but does the old advice of keeping registrar and NS separate to avoid one compromise hitting everything no longer apply?
