I think most regular developers do not really use 4M devices, as debugging them
becomes more and more annoying (my opinion). Support is still ongoing, however
release images will not be built for most (if not all), as a full build with LuCI
will not fit into the flash (even with 4K sector size).

The code is not really an issue, as there's not much code dedicated for 4M
devices. It's mostly their device-tree, which is maintainable compared to the previous
ar71xx boardfiles.

As many people still use these 4M devices (see, for example, the forum) - i would refrain
from dropping support altogether, but you will need additional effort in form of building
the images yourself (any maybe optimizing the kernel for the specific board building
the image for).

That's at least my personal view on the current situation.

Best wishes
