Enabling defaultURI (rust-url) as our default parser for unknown/fallback schemes in Bug 1603699 introduced significant breakage.
In addition to the user-specified list for custom schemes to bypass defaultURI as the fallback parser in Bug 1878001, this bug aims to provide a list of common custom schemes that currently encounter breakage during URL parsing with the defaultURI parser so that firefox can fallback to using simpleURI parser. We chose Remote Settings to distribute the list so that as we encounter schemes with enough breakage we can easily add to and deploy the list.
