Suggestion for divergence from prettier - consistent spliting of arguments with arrow functions

[RamojusLapinskas]

Given the following code, both prettier and biome will currently split the arguments inconsistently:

f(1, g(h(a => a)));

f(1, h(a => a));

f(1, a => a);

Output:

f(1, g(h(a => a)));

f(
	1,
	h(a => a),
);

f(1, a => a);

It appears that only when an arrow function is wrapped once in one of the arguments, the arguments will be split.

I think one of the following options would make more sense:

1. Always split the arguments when an arrow function is part of the arguments.
2. Never split the arguments based on whether an arrow function is part of the arguments.
3. Only split the arguments when an arrow function is at a certain wrap depth > x in one of the arguments.
