I think using conventional-changelog-preset-loader should be the best solution for #589 and reduce the burden on the @semantic-release/commit-analyzer maintainer.

Import loadPreset function from the package and use it to load the preset:

import { loadPreset } from 'conventional-changelog-preset-loader'
loadPreset('angular').then((config) => {
 // do something with config object
})
