It probably doesn't apply to this case, but if the documentation for a service says "invoke it this way" (and I don't just mean a "recommendation" or a "suggestion") and you choose to try something else that you think is equivalent, you are in unsupported territory. Do what you will; the risk is yours (and your site's).
There can be system integrity concerns with invoking something authorized in a way that it does not intend, when done by an authorized invoker. That could apply to an AC=1 program that you choose to invoke by (for example) LINK from an APF-authorized program.
