I don't know whether "error_page keeps 494 as 494 instead of
auto-converting to 400" is a bug or not. (I can imagine "yes" and "no"
both being justifiable answers.)

But if you *want* 400, you can do

  error_page 494 =400 /my4xx.html;

or, possibly for the specific case of 494,

  error_page 494 =431 /my4xx.html;

Hope this helps,
