I agree there is a body of evidence supporting the use of lyrica and gabapentin for anxiety and for gabapentin in the role of treating alcohol use disorder. I'm not strongly advocating for gabapentin but just sharing some of the data I am aware of.

But just like in the case of benzos which have evidence for anxiety, all medications have their place. Like any aspect in medicine, it boils down to risks versus benefits. These medications are helpful when utilized properly in the right cases. After speaking with some addictionologists, as I said earlier, it still beats Xanax or worse yet, things like THC and etoh. Likewise, in my high functioning patients with minimal addiction risk, I do prescribe some prn benzodiazepines. I don't prescribe benzos a ton, just like how I don't prescribe gabapentin a ton, but they can have their utility in the right circumstances. Of course, I always recommend therapy and exposure where warranted as well.
By the way, my cat's vet prescribed him buprenorphine and gabapentin =/. Just thought it was cute since on these forums we talk about addiction risk so much. He looks happy right now though, lol. I won't bore people with the details of his medical history.
