Yes. I can understand their reasons, that it permits lots of slightly different questions with inessential differences in the details, that are hard to merge. But people sometimes do have questions that have to be spelt out in detail and can only be summarized in the title, for instance in science and maths areas, or if it is something to do with their own personal situation and experiences. Or it might involve images or links, not just one but several.
There may be no single link that summarizes it. They may have to resort to writing out the details on another social platform, say, as a post on their personal blog, and then referring to it here which is clumsy.
Sometimes the answer you give, if they leave out the details, just won’t answer their original question.
Here is a mathematical example, the author drew a diagram and uploaded it to show what it was they were confused about in a simple question about quadratic equations. It's now a comment of course. Unless you look at the drawing in the comment, you can’t really understand fully what they were confused about.
SUGGESTED SOLUTION
Why not just move the question details into the comment section, as they are doing already. But do it as a special new type of comment actually labeled as “question details”.
So you can add the details but they are done in the comment section so hidden away. Make them communally editable also, as before. And the questioner can still say “(see details)” if they are essential to the question.
That would discourage use of details for unnecessary trivial distinctions, which would help with their stated aims - but without getting rid of them altogether for those who do need them?
(I put this idea forward before in Robert Walker's answer to Do you think Quora removing the question details feature was a good idea? )
