Alchemical Savant specifically requires casting through Alchemist’s Supplies as your focus. Does this make Enhanced Arcane Focus infusion useless for the Alchemist?

Alchemist’s 5th lvl Alchemical Savant specifically requires casting through Alchemist’s Supplies as your focus. Does this make Enhanced Arcane Focus infusion useless for the Alchemist? Or should that infusion work for tools also? The infusion requires a rod, staff, or wand.

Alchemists can benefit from it, but has no special ability to use it on alchemist’s supplies.

That infusion has definite “Wandslinger” vibes.
