Whitelist custom extensions in 6.5+

Background: Control 6.5 imposes a signature validation scheme to ensure the integrity of the Connect install (per this post). This is a net good for most of the community base. For the rest of us it's more trouble than it's worth.

Request: We need the ability to either whitelist custom extensions from validation or disable the signature validation scheme entirely.

Reasoning: I've developed quite a few extensions in an on-premise Control installation to automate significant portions of my business. I'm not willing to share some of this code since it exposes the inner workings of my business, sometimes usernames and passwords, trigger URLs, and plenty of other information that would be useless for the rest of the world, but could increase the risk of my own business data should it be shared with a third party -- even ConnectWise. Microsoft, Google and Adobe have each been hacked in the past, so it's safe to assume that anything I share with CW will eventually be exposed as well.

The hosted developer instance option requires me to share business logic and requires significant rewrites to the code for each of my extensions to be able to prevent business information exposure. Furthermore, as far as I can tell, some of the functionality can not be rewritten in a way that prevents this exposure.

I've submitted an extension to CW in the past and it took weeks to have it approved. It took weeks to be approved for a developer instance. I can only imagine initial approval of each of my extensions to be able to use them in my own on-premise install will take weeks as well, and even minor updates to my extension (such as cosmetic changes or field formatting) will likely take weeks to be approved as well. 

On-premise users require the ability to continue to use and develop our extensions without exposure to ConnectWise. Please enable us to whitelist our custom extensions within the web.config so we can maintain the integrity of our own installations and source code.
