I think you've uncovered a huge bug here in how these reviews are supposed to work, at least if I understand the handy-dandy review queues flowchart (from this post) correctly.
Here's the Late Answers portion of the chart:
Notice that there are supposed to be two outcomes from this queue: Looks OK/ Edit, and (Recommend) Delete. The former option leads straight back to "Full visibility on the homepage"; the latter, however, is supposed to lead to "...stays in queue until threshold met", which can ultimately result in the post being deleted.
So that's how it's supposed to work... let's take a look at how it's actually working. For reference, all users with access to the LA queue that lack the reputation to cast delete votes (users with less than 10k, myself included) see the "Recommend deletion" option in reviews, rather than just "Delete", so this isn't a small fraction of reviewers we're talking about.
If I dig into my past reviews and pull out one where I voted "Recommend deletion", I find...
...that selecting this option ended the review entirely. Huh.
Maybe a new review task is created for some reason?
...Nope. One single Recommend deletion ended the review.
Okay, this is a big problem. This means that, conceivably, no poor-quality Late Answers posts have been handled correctly by the system in reviews by non-10k reviewers since the queue updates (if, that is, this isn't a new development, which it doesn't appear to be).
To clearly reference your feature request, I don't think that this option should be removed, I think it should be fixed. Recommend deletion should either accumulate deletes, just like LQP does, or send the post into the actual LQP queue– either way would be an improvement, and would result in these posts getting dealt with.
At the moment, this queue is broken, which doesn't help anyone!
For reference, here's how a (since completed) review of a delete-worthy post in LQP queue looks:
Notice that there are multiple "Recommend deletion" entries by sub-10k users. The LQP flowchart has the same "Delete" flowchart box:The above reviews led to the deletion of the post attached to the LQP review above.
