Not entirely true. In a past life I've build loads of bikes with no additional paste flux- it all came through the hose. Gasfluxers come out of industry were there is a need to balance quality, volume, and clean up. Used properly they are great for brass or nickel brazing.
I currently use one for tacking, non bike stuff and as a redundant system for paste flux. I think of it as another tool, and treat it as such. I certainly don't consider it a crutch to hold up a sub par skill set or build method (nor do I see others using it that way?).
My bottom line- I absolutely do not need one, but like to have it for certain situations. I don't use as much paste flux as I see other guys use, but I don't lather on as much even when I'm not using the gas fluxer.
