In the dictionary definition of "traditional" it was common to have a piece of tape on the front of the riser with push pins, toothpicks, or other similar marked items used for sights. People also string walked and face walked for many many years. It's not like a sight was invented in the last 30 years of humans many thousands of years with a bow
In the current definition of "traditional archery" that is a big no no. I've always felt that "traditional" was a bad term yet I could never really think of a better one.
Unless you are shooting competition it is really up to you. I've seen people with a "traditional bow" using a release (I've also goofed off doing this. I shoot compounds some too and it is interesting to use a hinge release with the holding weight of a recurve - nice way to send a bow *really* flying through the air if you do not use a sling), sights only , elevated rests only, heck Ive seen (and played with, but really felt it was more a novelty) a wooden risered off the shelf bow with sights and a long rod with v-bars
Still, I come back to either "traditional" (wooden riser, off the shelf, no attachments, and single anchor/finger touching arrow), "barebow" (any riser, elevated rest, no attachments, and can face/string walk), or "open" (no release/peep in the recurve world) making sense as far as competitive classes go. More divisions than that tend to fracture the shooters too much and are really only trying to help edge cases - most recurve/longbow people fall into those three classes almost to a T.
Unless you are trying to compete or are looking for advice the main thing is that you have fun. Competitive venues require that people adhere to classes - it is really the only way keep a good even playing field where skill matter most. Of course if you are looking for advice then you either need someone who shoots that method or is knowledgeable about it (and best if they do both).
Otherwise why have less fun because someone else doesn't like what you are doing? I go to a shoot with what I want to have fun with that day and let the tournament director stick me where they thing I belong. There have been times I've been put (by the rules - no complaining here about it) in a class I have no hope of winning in. Lets face it, ASA or IBO has *no* class for an Olympic Recurve setup and if I bring it out I tend to be put into the open compound classes - only the top end Oly people are going to compete there and I'm not remotely one of them. However all is good as I'm there to have fun and I do (I'll even DQ myself in the competition if I feel like shooting from another stake - not gonna place/win anyway so shoot what I want), but were I looking to truly compete there I would have to change equipment (or rant at the governing bodies of that group).
