As Sheldon Brown mentions on his website, the vintage bikes with their horizontal Campy or Suntour drop outs are perfect for FG usage. These types of bikes are great fun and a very nice complement to geared bikes. The frame are sweet riding and besides that's what the racers from the late 60's and early 70's did. Those who could not afford a true track bike just removed the shifters, derailleaurs and freewheels in the winter and spun on a 16 or 17 T cog and held it in place with red Loctite and a bb lockring ( some derisively refer to this as a suicide hub).
I don't recommend backpedaling as it is not good for the knees (unless you ride an "urban" ratio in the 50-60 gear inches). I prefer to keep BOTH brakes on and ONLY pedal in the forward direction; but then I'm an official old fart and ride FG for fitness and spin and NOT for "Urban Hipsterism" tricks, and never brakeless.

PS A fixie conversion can easily be restored to vintage condition in less than an hour so what is the big deal? Now don't get me started on converting tubular tire equipped C&V bikes over to clinchers!

No hate from me, but after the dérailleur braze ons are filed off, for that 'clean look' it is tough to convert back. I have three sets of tubulars and one set of clinchers, all original, for my 80's Italian bikes. I ride mainly clinchers in AZ (too many thorns) and tubulars in MI. No problem with conversions, though I do hate seeing nice bikes ruined by removing braze ons.
