Rx under DEA scrutiny is nothing like rec or laughable state controlled medical 'recommendations'. You pull that shit as a provider on controlled scripts and your charts get audited, your DEA license gets pulled.
Imagine a noncitizen in that situation being able to tell a border officer, or a citizen being able to tell a security clearance investigator: "Yes, I do use THC. Here's my prescription and the bottle from the pharmacy." and being confident of no negative repercussions. Wonderful progress compared to where we are now.
You could already get THC script, in that context this seems like a half hearted concession for flower to stall and poison legalization efforts by giving a victory poisoned with DEA licensing that inserts the nasty tendrils of the weed hating DEA into medical flower.
