Response Header Extension

I need to add the extension listed in this post to my on prem Control server. However it now needs to be signed.

Please add this extension to the market place so it can be easily installed.

Signing up for a cloud account, requesting developer access (which the request process is currently broken, ticket 11878822), create the extension, wait for it to be signed, download it, install it to on-prem is a very long process for something that should be very simple.
