I've added a spreadsheet of ringed stars that are not brown dwarfs. Currently it has 5,455 entries, but I know there's at least one small gap in the data. I had to back-fill the database with rings (I wasn't previously storing them for stars), but the current nightly dumps on EDSM have a gap of a few days. The full dump is about a week and a half old, which I was able to supplement with the 7-day dump, leaving out a few days. I'll have to run another back-fill later.
Even though it has only a little over five thousands entries, the list would be considerably shorter if I were to exclude T-Tauri stars, which I'm tempted to do.
