What problem does this feature solve?

In version 16.8.1, Index.js has a piece of code：

if (!/\.vue(\.html)?$/.test(loaderContext.resourcePath)) {
    // ts-loader does some really weird stuff which causes vue-loader to
    // somehow be applied on non-vue files... ignore them
    return source
  }

therefore, this loader cannot be used to convert the markdown file. some md loaders, such as vue-markdown-loader, cannot take effect.

What does the proposed API look like?

please let go of the conditions here，apply to .md file
