Or <classSecurity>, because it's class-based. Good idea.

Perhaps. Of course, practicality sort of wins here because we already
have top-level <allow> and <require> directives for making assertions
about modules.

Why? I respect the vote but so far I haven't heard a reason for it.

True. Which is why I would defend class/require and class/allow as
subdirectives (instead top-level ones). The reason why I'm not defending
class/implements is because I'd like to consolidate.

Especially in Five, but I can imagine also in other projects, you'd like
to declare interfaces on classes without configuring their security.
Five invented five:implements for this. In Zope 3 this is not possible.
Also, neither in Zope 3 nor in Five it's possible to declare an
implemented interface on a function (I actually have use cases for this,
of course I could deal with them differently, but a uniform way would be
