Of course it does, all I'm saying is that we revival singers (of whatever generation) operate at a very significant remove from the original context in which the songs came about.

I sing them & perform them, but I don't fool myself into thinking that I am a Traditional Singer, rather a Singer of Traditional Songs, which is something very different.

As for tunes - my advice is always to proceed with caution and get as close to the source as is humanly possible. How often do we hear (say) the melody (& chorus) of Lay The Bent to the Bonny Broom (Child #1) sung to the entirely innapropriate ballad of The Cruel Sister (Child #10), just because Pentangle (for whatever reason) choose to do so?

I recently started singing The Cruel Mother to Mrs Pearl Brewer's superlative melody, as can be heard as part of the Max Hunter archive; I use a different set of words however, but I always point out my sources in performances.
