I know this because I work for two single-blind peer-review journals, and we’ve received submissions formatted for double-blind review. We don’t bother because, like your field, ours is narrow, but there’s a lot of research, and we can’t publish all of it.
For you know of any journal/field that does double blind? Genuinely interested.
In my field, there are so few experts we can often know who was the reviewer based on their comments.
I know of several journals, such as this one… ONCOLOGY, NUCLEAR MEDICINE AND TRANSPLANTOLOGY https://www.onmtjournal.org/home/peer-review-policy
