To enable it you had to provide the 'allowsuperpage' parameter so by default
nobody would use it. Which means no security support (like the #UD traping
for cross-vendor migration).

I somehow assumed that any non-default enabled parameters by default would not
receive any security support.

Like running an 'debug=y' kernel or such?
