Get rid of foaf dependency in ACLs?

I wanted to highlight this issue raised by Sandro Hawke relating to

https://www.w3.org/wiki/WebAccessControl

"Servers are required to recognize the class *foaf:Agent* as the class of
all agents. This indicates that the given access is public. In some cases
this will mean that authentication is therefore not required, and may be
skipped. When a resource is being written, however, it may be necessary to
associate the change with some kind of ID for accountability purposes."

Here is the issue:

I think proposal is to change this to rdf : Resource to be more general.

Any thoughts on this?
