Packaging Chromium as an extension request

[jstone]

Some applications may need to leverage Chromium for rendering content if pandoc isn’t sufficient, which means apps may need to do either of the following:

A) Bundle Chromium with the flatpak application
B) Call Chromium through flatpak-spawn

Here’s an example:

Marp-slides plugin export function will not work

Having Chromium available as an extension would avoid the security issues of calling flatpak-spawn and avoid the maintenance burden of building Chromium.

Adding optional support within an app may look like this:

add-extensions:
  org.freedesktop.Sdk.Extension.Chromium:
    version: '22.08'
    directory: chromium
    no-autodownload: true
