Share static and assets folder between sites in multihost mode

Is it somehow possible to share the same static assets (images, downloads) and resources (stylesheets, javascript) in the output of a multihost configuration?

I would like to achieve the following outout:

    # languages
    # assets + resources

My setup will be multiple baseURLs but hosted on the same webserver and as such it would be nice to just have one export of all static assets that are shared across all sites instead of having the data multiple times in the export.

I could potentially generate the resources, remove them in all but one language and symlink all other but that seems like a waste of processing time. Any smart and more intended way of achieving this?

I would certainly not say intended, but as mounts can have a lang attribute, you could maybe create a “pseudo language” for your common stuff.
