What problem does this feature solve?

We use the following base config

base: /page/index.html

what we want in href generated by

<a href="/page/index.html#/foo"/></a>

what we have now

<a href="/page/index.html/#/foo"/></a>

What does the proposed API look like?

base: {
    url: '/page/index.html'
    trailingSlash: false
}
