Would you mind also listing in the cover letter the examples folks have
provided on the RFC of distros etc validating that this is a common
choice even for openwrt these days? Also I quite like Geert's analysis
of kernel growing by this much anyway so this isn't a huge jump :)

When you repost could you trim the "(open list:.." stuff form the CC
lists? For lists just the email addr is enough, no need to quote the
rest of get_maintainers output.
