If you polish the edge of the nose, you're looking at a potentially hazardous configuration. The hammer notch is the most difficult area to work on, which is why we stone it.
If one takes a polishing wheel to it and goes to town, thinking they are polisherin' her up real nice, and ends up with a rounded trigger nose, it's a bad thing.
Following the advice and mentoring of very respectable gunsmiths, I have performed the work on my triggers, and ended up with much improved trigger feel, with a long-lasting trigger that has never resulted in failures, doubles, etc. The first one I ever did was on one of my 3-gun carbines, and I took that gun to over 10,000 rounds of high volume fire before breaking my bolt at the cam pin hole. The trigger never malf'd on me because I did exactly what you describe, and didn't change the angle of the surfaces.
I've done it on several triggers over the years with successful results. I have also seen a few people bugger up triggers, mostly on 1911's though. Some factory 2-stage triggers are non-functional in the AR15 and AR10, and need to be looked at by a competent thinker, regardless of what is next to their name, or what training they slipped through for the cost of admission.
You may not be but to say what you said some people may take a buffing wheel to their triggers and screw them up. The angles have to be maintained and any home trigger jobber needs to understand that.
