Ok, granted.

I don't think so, as I tried to explain.  If you don't know what the
method means, you're not going to invoke it, even if it's safe ...
except perhaps for "ping", as you mention.

I believe that safety should be defined wherever the method semantics
are defined, and that ain't the WSDL.
