I strongly disagree with that we should sacrifice accessability and i18n on
the altar of fingerprinting concerns. There are situations when that may
be necessary, I don't think this is one of them.

The HTTP header "accept-language" defined by HTTP 1.1 section 1.4.4
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html already provides the
users locale. A users locale has a strong correlation to a users keyboard
layout. If the intent is to avoid adding identifyable bits by preventing
locale sniffing that train is gone with accept-language. The additional
keyboard layout information is mostly superfluous for fingerprinting.
However without some way to query the layout for a users key symbol,
usability of shortcut mapping dialogs is extremely crippled.
