We have considered this, at one time. You can have the same effect by using an 
indented literal scalar. The benefit of the "terminated" style is that you 
don't need to indent the scalar. From a YAML point of view, that's a 
disadvantage; the document structure becomes much less visible.

It almost seems as though this should be a flow style rather than a block 
style, since it uses a marker rather than indentation to denote structure. 
The following doesn't make much sense, though:

	---
	some:
		flow: { terminated: <<EOF
	Text
	EOF}
	...

Perhaps if someone comes up with a use case where indenting the text is a 
problem? The problem isn't long lines (for these, you need to use double 
quotes anyway). Admittedly, indenting literal scalars costs screen real 
estate, but they have to be pretty deeply nested for this to make a real 
difference (you can indent each level by just one space if you want).

What's the use case?

Have fun,
