"in the order they were included in the main line kernel" Out of trees aren't in main line.
And "This is an arbitrary convention" specifically says it's arbitrary.
There is literally nothing here stopping out of tree modules. I have proven this, and so have you with these quotes. What is left to object to?

*For main line kernels*
Please, understand both the *intent* and *reality*: this does not block out of tree LSMs, full stop.
