Ok keep two modes if you want ...
Let's only talk about the modern mode !
I wanted to really use commuting labels, I was ready to change my habit,
but I found them to restrictive. I find my proposal, which is just to
change a bit the semantics of function application (and nothing else) on
non-labelled arguments quite nice and useful (no need to always remember
all the label names if you prefer to remember the order of the
arguments).
As my proposal only cost to change about 20 lines why not have an option
to the modern mode to let people try it for real and see what they think
?
About the "so wonderfully clean theoretically" .. it is not so clear:
look at this example:

I could live with this kind of problem ... but in the current version
labels are more painful than useful in modern mode (this is my opinion)
