as Chris already said, if it's an opt-in feature the user needs to 
actively confirm, I don't see an issue with including it.

Regarding HTTP requests, the current approach would be either using the 
new OvmsNetHttpAsyncClient class (components/ovms_netlib/ovms_nethttp), 
or using Mongoose directly.

OvmsNetHttpAsyncClient is meant as a replacement for the old http-only 
OvmsHttpClient (main/ovms_http), but hasn't been used in the master 
branch yet. There is some new work on this in the for-v3.3 branch by 
Chris regarding timeout handling, but the class should work in master as 

An example on using the Mongoose TCP API is in the Pushover class, and 
another one in the DuktapeHTTPRequest class using the Mongoose HTTP API.

Mark has included a JSON parser in the for-v3.3 branch, if you need one, 
have a look at that first.
