Nope.  And, I was sure, but wrong, before.

The man page does say:

       In these commands, an address can be any of (a) an IPV4 address in
       a.b.c.d format, (b) an IPV6 address in [a:b:c:d:e:f:g] format, (c) a
       link-local IPV6 address with an interface specified in
                                       ^^^^^^^^^
       [a:b:c:d:e:f:g]%device format, or (d) a DNS hostname.

But on re-re-reading it, that 'interface' is not the same as 'interface'.

Good grief...

Another part of the man page agrees with you:

   interface [listen | ignore | drop] [all | ipv4 | ipv6 | wildcard | name
	      | address[/prefixlen]]
[...]
    That parameter specifies a class of addresses, or a specific
    interface name, or an address. 

So it can do either address[/prefix] or the name of an interface.
More weird....

That would match the more specific part of the man page.  And makes it
even more confusing.   One keyword for two very different things.
