After a question is put 'on hold', the first time it is edited (if within 5 first days after closure), it is automatically sent to the reopen review queue (see How do you reopen a closed question? and What if I disagree with the closure of a question? How can I reopen it?), where it receives a greater chance of getting attention and being reopened.
But I have observed, frequently, this automatic sent to the reopen queue comes with an irrelevant edit to the motive the question was put 'on hold' (example, someone else than OP remove 'Thanks'), hence, it remains closed. If the OP (asker) later edit his/her question, it won't automatically be sent to the queue, and will depend on >3k rep users casting a reopen vote to sent it again for review.
I have expressed this concern before in this post: Is there a limit to the number of times a question is eligible to vote on to reopen after it has been edited?
I would like to know what the community thinks about carrying on edits in 'on hold' questions, where such edits do not address the reason the question was put 'on hold'? Are they ok?
Because I believe the benefits of such types of edits (better readability) do not overcome the possibility of a question not getting reopened. Another downside is that editing 'on hold' questions (when the edits are irrelevant to the the close reason), bumps the question to the active page and reduces time of visibility from new answers.
Important: I am not referring to edits like removing 'thanks' and other kind of noises, fixing typos and grammar, editing tags, better title, etc, to questions which are opened, but only the ones with 'on hold' status.
