Please export `PsbtInputExtended` and `PsbtOutputExtended`

So that I can remove following code in my project

// Following types are not exported by BitcoinJS, so they need to be manually extracted
export type PsbtInputExtended = Parameters<
  typeof bitcoin.Psbt.prototype.addInput
>[0];

export type PsbtOutputExtended = Parameters<
  typeof bitcoin.Psbt.prototype.addOutput
>[0];

We need to evaluate it.
Is there any deeper reason?

addInput and addOutput are public APIs, so I think you should export the public param types too.

I will use these types because I need to define functions like

function buildPsbtInput(...params: MyParams): PsbtInputExtended {
  // implementation
}

const input = buildPsbtInput(myParams);
psbt.addInput(input);

Maintainer triage: accepted as DX/typing feature request. If anyone wants to contribute, a focused PR exporting these types with tests is welcome.
