@FBM,
Bob Hazen, a colleague from Carnegie, has been working on the hydrothermal vent and pressure model of abiogenesis for almost 15 years. He made a presentation at a conference about 8 years ago and was snickered at by all the old Miller and Urey people who were only then making adjustments into the pre ""spark" conditions that M&E combined.
Everyone is now using pyruvates in a hydrothermal vent "Hypothesis" and its showing the shortcomings of relying upon a single mechanism like Miller and Urey in a reducing environment or failing to include pressure vents in with the chemistry.
All we can see is that an "RNA world" mechanism needs more "interdisciplinary work".
Leadfoot has already stipulated to the "ease " of accepting the continuing role of evolution ,even though the same chemistry is basically involved with life exploiting an entirely new (often quite toxic to the existing life ) niche, than the previous. The same "readjusting" of the peptides and metabolites would be necessary for the new classes of life as were needed for the previous.
As you say, new evidence appears daily and the "god squad" paints itself into an ever decreasing area in their corner
