I've always said that we need to have a notion of endpoints that "support ECN" and ones that don't. This does not need to be negotiated, but it reflects reality. Some impls will implement ECN support and some won't.

To the question of whether there is a good reason to not do it: Yes, implementation complexity for little gain. I'm not arguing for not implementing ECN support, I'm saying that there are good reasons for not doing it.

If we want to encourage ECN, we need to simply say that. And the text should reflect the reality that some endpoints will choose to still not support it.
