I'm not disagreeing. Marking unmodifiable arrays as const is generally
useful for readers.  Decent compilers though can _mostly_ determine
whether or not an array is used as const and whether the array can be
placed in a readonly section and is not required to be in a writable one.

But the object sizes deltas you show with an allmodconfig are misleading.
At a minimum I think you should show the output sizes as allmodconfig.
