Yes.  It's such a small feature, yet has a huge benefit.
People should use it more often.

Another small feature: underscores in numeric literals.
One of my pet peeves is when I have to carefully
count the zeroes in 10000000, when it's so easy
to write 10_000_000.

Do you have any examples of that last part?  That is, examples
where using different parameter orders in different calls
makes the code more readable?

I think that sort of inconsistency usually makes the code less readable.
I wouldn't mind a rule that says the parameter order has to match
the declaration.  (A Legality Rule, not a Name Resolution Rule!)
