"Why CI/CD Still Doesn't Include Continuous Documentation?" (current title) is an interesting direct translation mistake, in the question form. I see it often, and it makes sense.

English doesn't have a succinct way to frame the construct. I wonder if this form will eventually become correct.

Alternatives:

"Why (still) doesn't X do Y?"

"Why is it that X still doesn't do Y?"

"Why doesn't X do Y, still?"

All of these are awkward, but more idiomatic. Currently, at least. :)
