Sometimes, when a developer adds a string to En resource file, (s)he adds it as well to all other non-En resource files.

Isn't that unnecessary?

http://wiki.winehq.org/SublangNeutral says the search order is
  1. LANG_NEUTRAL, SUBLANG_NEUTRAL
  2. LANG_FRENCH, SUBLANG_FRENCH_BELGIAN
  3. LANG_FRENCH, SUBLANG_NEUTRAL
  4. LANG_ENGLISH, SUBLANG_ENGLISH_US
Would a patch removing En resources in non En rc files be accepted? This would allow for more accurate translation stats.

Or doesn't a fallback mechanism always apply?
