I think this is because of the nature of 408 error. It means the client
is slow, (or slowloris). Probably the only sane thing to do in that case
is to drop with an error. Though, looking at the documentation it seems
you can configure when a request is slow with this directives:

client_body_timeout
client_header_timeout

Check her e for more details:

client_header_timeout
