If a programmer wants to format just the first argument, then this is the code
Introducing/keeping a muddy semantics to avoid writing one more function call
like is not a so good design.
Keeping designs semantically clean is usually better, because it helps avoid
bugs and more importantly it avoids unexpected corner cases and unwanted side
The introduction of a special case with muddy semantics is sometimes
acceptable, when it gives _significant_ advantages, that means it makes
something else significantly more handy or significantly simpler, etc. But in
this case I think it makes code only a bit more handy, while increasing the
probability of bugs.

This is better than the current situation.

Usually explicit is better than implicit. If this is the desired behaviour,
then the right thing is to use/introduce an explicit syntax to do it.
Positional arguments are meant to do this, I presume.
