"Interesting. Could you offer any detail on how
you dealt with trays, spills and wetness in general,
an overview of the workflow."

In times past I used the usual three tray procedure.
Spills and wetness? I don't recall those as being issues.
Perhaps less solution volumes were more the practice.
Undoubtedly some little clean up was involved. Today
I process on a counter and have only a few drops
here and there to wipe up.

"I'm not picturing your setup or process clearly,
and think it a very intriguing concept since it runs
at odds with my preconceptions."

"I have always thought of the general purpose
darkroom sink as a counter top or workspace with
an edge to contain liquids. Basically a wet table."

"...a counter...with an edge..." I'll allow for that but
not the "table". A table I think of as being a free
standing support.

So where to draw the line twixt counter and sink?
Characteristic of sinks are: 1 - a drain, 2 - a bottom
which slopes toward the drain, 3 - an inclosed recessed
space, 4 - and equipped with running water.

A counter has none of the above but is level and may
have a forward very low edge.

"I haven't ever used a really deep edge. I have always
tried to get as much horizontal sink space area as possible.
But your commentary makes it sound like there may be a
very different approach and I'm interested."

Nothing revolutionary. At least in years gone by sinks
were integrated with the counter. The sink was used
for preparing chemistry, washing up, and may have
held any washing apparatus. Dan
