It seems at least here, that the opinion is that informative comments ta should be deleted, and wonder why that was so?
Informative comments should be avoided because they can be deleted at any point, and extended discussions should be avoided. Any information required to answer your question should be contained within the question itself. Once you have several discussion the comment section can be extremely difficult to read. There are a ton of meta questions on the purpose of a comment to confirm, that comments are temporary, and only information contained in an answer or question is permanent.
Can a moderator from another community delete my comments in our community?, is a single example, that the community could use to defend avoiding having information contained within a comment.
Although yes, some information should be edited into the original post, some questions that are asked in the comments may not actually the pertinent to the question the OP has asked.
If you provide the information in a way that sums up the questions you received then you have allowed a moderator to remove two unnecessary comments.
Adding details of what is irrelevant based on questions on comments would seem silly and just bloat the question out.
You shouldn't assume the questions asked in the commentary is irrelevant. If somebody believes the question is important to be asked, then you should address, or flag the comment as not being necessary.
The deletion of the comments, as well, would mean that other volunteers would be deprived of the knowledge. That seems quite counterproductive.
If the information is not important enough to be contained in the answer, then the comment, isn't necessary and should be deleted.
If the response, by the OP, does add something to be edited in then yes, then OP should be encouraged to do so, but it seems odd to flag that comment for deletion; or more so to delete the original question itself. It feels quite counter-intuitive.
In your particular case. I specifically requested you submit the information, as an edit to your question, but instead, you provided the information in an abbreviated comment due to the limitation of a comment itself. I always ask people to submit the information as an edit to the question instead of a comment.
If the OP were to respond, and then, perhaps, not come back to the question till the following day that comment may well be deleted, and more people have asked. That does not make a good experience for the users.
If a comment is deleted then it wasn't necessary. If the author didn't update the question, then they either felt the information being requested wasn't necessary to answer the question, or simply didn't feel like providing the information. In either case, it is not typical delete comments that haven't been addressed, but important information should be contained in the question instead of comments.
