Recessed brake mount filler?
Hello. Doesn’t someone make a nylon filler to go in here?

If you have an Ace Hardware store near you, they should have a decent selection of black plastic and chrome push-plugs. I've also had good luck on Amazon, with some careful measuring of the desired head size.

I'm curious. Was there a need to fill the brake binder hole (and thus not have a brake), or a spacer so that a non-recessed brake could be used? If the later, please share what you found, a lot of people would have a use for this. I don't recall ever needing one, but it would make sense.

Yeah, I’ve bought them from Rivendell in the past, but I’m sure a good hardware store has a suitable nylon bushing.

Dia Compe also makes them. I have a pair somewhere left over from the 4 pack I bought a couple years ago when I built the Bianchi (with nutted NR brakeset) for the Eroica auction in 2018:

This was a special rear brake bridge that was sold in the late 70's or early 80's (I can't exactly remember) with a special brass insert that just fit into that 1st recess. I remember them being a Cinelli brand item but of course they were probably sold under other brand names as well. I'm not where I can take a picture of what they looked like. I brazed them into a number of frames I or my frame building class students made back then. I remember being worried because when overhauling or repainting a bike they could be lost and there wasn't a supply of spares. If lost the whole bridge had to be bought again just to get that little part. Probably because that insert could be easily lost and costly to make, they weren't sold for too long of a time. However because brake bridges tend to be bought in volume they could have been used in manufacturing frames long afterward.
Of course there are other ways (some already mentioned) to turn an 8mm hole into a 6mm one. For example I have a lathe and know how to use it. However the original brass insert was pretty sweet.

I have one bike with nutted front brake that has what appears to be a Presta to Schreader valve stem adapter pressed into the rear hole in the fork crown.

I would only use metal for any part that in any way sustains bolt tension or supports the caliper or stud.
You can't tighten against plastic and have it not compress over time, requiring repeated tightening.
Or am I misunderstanding the intent here?
I took a couple of cuts off a 6mmIDx8mmOD aluminum spacer to adapt nutted Superbe calipers onto my CAAD3, I think it was as simple as that.
Metal washers can be found in an infinite range of dimensions to fill the little counterbore.

Rivendell is mentioned quite often here for sourcing bike hardware.
Last year, I finally got to visit their place in Walnut Creek (A bit hard to find) and was surprised how sparse the place looked and there was not that much to see in terms of hardware and components. Just a couple of bikes kinda haphazardly parked in their entry space for display and a couple of small showcases with mostly literature and decals at that time. There were a lot of cyclists hanging around the front door, but it seems like most of them were just staging up for their morning group rides and were not really going into the store. Was also very surprised that they did not have the axle spacers I was looking for that day. I was quite perplexed and did not know what to make of Rivendell coming away from that visit. It sure fell off my list of bike places to visit/shop in after that. Maybe I just don't get what Rivendell is really all about?
