I would say that it is most likely that any mod that automates aspects of the game or changes its graphics in such a way that whoever uses it obtains a significant advantage over those who do not use it will be considered unsuitable for use in a competitive environment. That does not necessarily mean not allowing it to be used, but it does mean that its use is confined to "friendly matches", without rating/points or any other type of competition.
We could again use as an example the small trees of age of empires 2 that have become a standard and are available to everyone even in competitive environments and, on the contrary, mods that automate aspects of the game in some way have been prohibited, with some exceptions like the cavalry's Auto-explore.
