Vendor defined U-Boot has changed the partition scheme a while ago:

* kernel partition 6MB
* file system partition uses the remainder up to end of the NAND
* increased size of the environment partition (to get an OneNAND compatible base address)
* shrink the U-Boot partition

Let's be compatible (e.g. Debian kernel built from upstream).

That, in fact, is breaking compatibility.

With what? Nobody is using the old u-boot partition scheme any more
(it is >5 years old).

So once you are touching this
what about relying on partitioning provided by bootloader just to prevent
something like this happening again?

Well, we define what compatible means here (since we are the vendor).
And people complain with us. We simply recommend them to upgrade the
boot-loader.

I should also mention that a modern and fully configured kernel binary is
already too big for a 4MB kernel partition.
