This is probably best to leave as is (until v5). Adding/exposing another public API variable, and now having to maintain two exactly same errors (with different name), has longer effect than having little bit unfortunately named variable.

@lammel what do you think?

This section was revised in PR #2277 . Seems like we overlooked a chance to correct the naming there.

Not sure how often the old const is used in the wild (for me it's about 1 of ten projects)
I'm not completely against adding a deprecation in echo v4, but v5 is around the corner and deprecating it would mean we could remove the wrong value with v5 already then, which seems a little to sporty. But we don't have to of course.

As it is a pretty minor change I vote for approving the change and get the errors clean.
