Main Delegate Is Called By Monobehavior?

I used void Main() as a method, and was having a bug. It was running on its own. Renaming it stopped this.
I was wondering if anyone could produce some documentation supporting where unity explains the purpose of this function. I was under the impression main was not a protected word in unity even though we use C#.
Also, even if it were, it is Title Case unlike the core method in c#, so it shouldn’t be initializing as far as I have knowledge.

FYI its acting like the start method, if anyone is curious.

Thanks for any input.

Up from the version 2020.x its disabled,
it was not documented by Unity so i assume it was kind of a sneaky “bug”
