Should OP invoke ngrok?

Support have replied to me

I'm happy to help provide some context of that ngrok version check.

Thanks for pointing this out - we do have a check for the version of the ngrok however it's supposed to only be run when a user is making use of the ngrok shell plugin. The Development team has been informed and will be moving this invocation to only be used after the ngrok shell plugin is invoked. We only check the version of ngrok installed, and do not otherwise use or invoke its functionality.

This behavior does not have any security ramifications but is definitely unexpected behavior. We have logged a feature issue to rectify this unexpected behavior and my apologies for any inconvenience it has caused! If you are interested I can track this issue and as any updates occur I can reach back out.
