Automation Support - why not also apply to "skills" granted by items instead of just "spells"

Automation Support is an interesting direction that buildmakers can use to build more complex interactions. However, there are items that grant "skills" which are not counted as spells and therefore Automation Support does not affect them. I don't see the rationale for making the support count only towards spells instead of more broadly.

The particular interaction I'm referring to is the skill "Embrace Madness" granted by the "Beacons of Madness" boots. It is an "instant skill" instead of an "instant spell."


Maybe the real suggestion here is that Embrace Madness needs to be reclassified as a spell?
