Comment (by mihai2u):

 "duplicates a near identical API" -> since this a feedback for applying
 Don't Repeat Yourself principles to the code, yes, it's a nice to have,
 but as specs evolve, that might introduce more complexities down the road
 than combining the functions or APIs would.

 I can give one relevant example - preloading a module JS requires a
 different syntax:
 <link rel="modulepreload" href="dog.mjs">

 And with a separate implementation, this logic can be baked in the preload
 logic much easier, like when passing a "msj" parameter for the as, to
 change the output to match the specification:
  [https://developer.chrome.com/blog/modulepreload/]

 My suggestion is to keep this as it is for the flexibility it provides for
 having the code separated.
