Yeah, I made the same "discovery" some time ago.  Since then I've been
using something like the following to restrict my-rsc to my-node:

<rsc_location id="restrict" rsc="my-rsc">
  <rule id="restrict-rule" score="-INFINITY">
    <expression id="restrict-rule-expr" attribute="#uname" operation="ne" value="my-node"/>
  </rule>
</rsc_location>
