Inconsistance throwing behavior on String and Regex's xxMatch

We have public func wholeMatch(in s: String) throws -> Regex<Output>.Match? method on Regex and public func wholeMatch<R>(of r: R) -> Regex<R.RegexOutput>.Match? where R : RegexComponent on String.

Their usage is something like the following and IMO they can exchange in some extend.

let regex = /Hello/
let input = "Hello world"

try regex.wholeMatch(in: input)
input.wholeMatch(of: regex) // The result is the same as the above

So my question is why one is marked as "throw" and the other is not. Should the throwing behavior be aligned?

Apologies if I missed something already discussed before.
