Note that build mode doesn't support a bunch of other MD raid features either, like all of the parity raid levels. That it doesn't support v1+ metadata isn't a surprise, and isn't the only legacy feature that only uses legacy metadata (built-in kernel auto-assembly gets the most whining, actually). Anyways, though I can't speak for the maintainers, it seems that build mode is there to keep the MD maintainers from being yelled at by Linus for breaking legacy setups. Nothing more. If you think its trivial to implement --build with v1.x metadata, go right ahead. Post your patches for review.
