Feature Proposal

Ability to disable "middleware delays requests until compiling has completed." for custom proxy middleware

Feature Use Case

Forwarding API and Websocket requests to a separate Node.JS process. Today, all API / requests need to wait for the entire frontend rebult to complete which does not seem necessary.

It needs to run on the same port so it needs to reuse the http server. A viable solution would be to allow hooking before the "wait for changes" middleware is set up.
