Feasible to recognise `.biked` (HogBay Bike 2 textbundle) extension ?

If images or other files are dragged into a (Bike 2 Preview) .bike document, the user is offered the option to save the result as a .biked textbundle, containing:

1. an assets folder,
2. an info.json, and
3. a flat text.bike file.

Marked can already preview the text.bike in the bundle if we:

• drill down to it directly in the Finder, or
• provide its full path in an x-marked-3:// url

but I wonder if it might look feasible to recognise the .biked extension and automatically preview the text.bike which these Bike-flavoured textbundles contain ?

Convenience apart, the main user value would, of course, be the previewing of images located in \assets and referenced by image links in the bike document body.
