Description

I don't know what this means:

pMemoize(fn, {cache: false})

I have to document it every time:

pMemoize(fn, {cache: false /* only while pending */})

The module can export a more readable helper instead:

export const pMemoizePending = (fn, opts) => pMemoize(fn, {...opts, cache: false})

Note: the types of opts should exclude cache

Some tags could also be added to package.json

Research direction
The implementation requires adding a new exported function pMemoizePending in the main entry file (likely index.ts or src/index.ts). The function should accept fn and opts, excluding the cache option from opts. This is a wrapper around the existing pMemoize function. Review the existing TypeScript types for pMemoize to ensure the exclusion is correct. The package.json may also need tags added. Since the issue has an assignee, it is advisable to coordinate with them before starting work.
