There are other cryptographic things users could be doing on the
server side, too, via extensions, or even other library dependencies
that themselves rely on OpenSSL.

But in any case, what you've written seems reasonable to me, and I
don't have any reason to gum up the works, so I'll pipe down. (I've
asked around internally to see if there are any concerns, too; I'm
happy to share if I find anything.)

Thanks!
