"1.) Most garbage disposal manufacturers warn against shoving piles of
peelings down the disposal, so it makes sense to peel into something
you can empty into the garbage or a compost pile. "

I've never seen this from any disposal manufacturer. They do caution
against putting certain things down the disposal, like corn cobs, but
I've put a lot of peels and vegetable products in disposals for years
with no problems. That is one of their main points for me.

"2.) Even if you decide to peel into the sink, who cares if peels get
soapy, or get pasta water on them? It's garbage. You really don't do
"food prep" on the dirty bottom of a sink. "

No one mentioned wanting to keep peels from getting soapy. What was
mentioned was having one bowl with peels, dishes or soap foam in it and
being able to use a second clean bowl for other use, like putting a
collander for pasta in.

3.) When someone needs to drain a big pot of boiling pasta water,
you're going to get out of their way anyway, and it takes mere seconds,

so a divider isn't needed.

I don;t know what this has to do with one or two bowls.


"After two years of putting up with two basins, I realized one day that

not once in all that time did my wife or I ever need or use that
divider that was getting in the way and taking up valuable sink room. "

I use two bowls frequently enough that it is a valuable feature for me.
Which shows why manufacturers make them both ways.
