I don't think anyone in the security community would find it reasonable
to expect all devices with global IPv6 address to operate in a secure manner.
"Secure" is a relative term.

Let me rephrase this to be that any device that configures a global IPv6 address should expect that it may be connected to the global IPv6 Internet and act accordingly.

There is more than enough evidence to suggest that in practice it will be
exactly the opposite.
Perhaps if more devices were exposed to the Internet, they would operate in a more secure manner.
And remember, in the typical SLAAC scenario any device that understands RAs
will automatically get a global IPv6 address, there is not much you can
do about it.
But you don't have to open sockets that listen on that global address.
