I does not matter at all! You are proposing a part of ABI which will
be closer to what is "carved in stone". Here is the problem.

So, I'm really trying hard to get avoid such "small things" which
would make our lives quite hard in long term prospective while fixing
short-term issues in a good will.

Please, consider to do it better. For now I didn't hear any proof that
there is no other way to achieve your goal.
