nitpicking :

could we simply declare a
     .section __discard,"",@progbits instead ?

I think this should remove the need to tweak the linker script, since
the section would not be allocated.


The allocation flag is a loader property, not a linker property. It would still be manifest in the vmlinux file; I think this is undesirable. Perhaps not a big deal, but neither is adding a /DISCARD/ statement to the linker script:

/DISCARD/ : { *(__discard) }
