It would be nice to get JEI compat for alchemist hammer, some players on our server are confused and think that there are no recipes for powders, since jei is not showing that you have to use hammer on ores to get them.

1.15.2

I will research how to do this.

Will this be sufficient?

Fixed in latest release. Added JEI info pages for Alchemist Hammer and Alchemist Wand.
