Is it safe to disable the stop/start system?

I want to permanently disable the stop/start feature on my Skoda Octavia Mk3 (based on VW).

_{TL:DR; The implementation is faulty. Suppose I want to pass a parked car, and slow down for a car coming the other way. I might still be moving, and in gear (auto) yet the engine cuts out, the steering loses power, and I can’t complete the manoeuvre. I’d go so far as to say it is dangerous. But you have to disable the system every time you start the car, and I do not always remember. Anyway I can and do switch off the engine when it is not needed.}

VW claims it is not possible to disable the system but I found there is a connector from one of the battery posts which monitors the state of the battery, to check if there is enough power to run the lighting and aircon, and restart the engine. If disconnected, the stop/start system does not work.

The post I found says

I have a very good friend who is a master tech at VW and a bit of a car genius too……..he did it without me knowing! Its a simple little plug and if he tells me that its only there to inform the start stop function then I absolutely trust him.

I do not want to try this if it will cause something bad. So, my question is:

• If I disconnect will it affect the normal charging of the battery, or anything else?
