Simplicity is relative to the knowledge of the dev doing the work. But it
is relatively simple. In GStreamer Bayer formats have their own media type
(video/x-bayer). There isn't a libgstbayer library for it, so no custom
stride/padding can be used for now (since nothing is ever set in stone)
though it's much easier. In general, if you add the missing formats, we
request a basic implementation in bayer2rgb and rgb2bayer software
elements. This is extremely useful when using and debugging.

Note that "some" patterns are already supported. If it's the case, you just
need to map these into libcamerasrc.
