Here's what the description for VLQ reads (with added emphasis):

This answer has severe formatting or content problems. This answer is unlikely to be salvageable through editing, and might need to be removed.

We handle our VLQ flags keeping that as the baseline. On that basis, we may decline flags if we disagree that the post is of very low quality.

Quoting from Tim Post's answer on What kind of answer should be flagged as "Very Low Quality", but not flagged as "Not an Answer"?:

If a moderator investigates a very low quality flag and sees an answer that is readable and seemingly relevant to the question, well .. there's not much evidence of a quality issue.

If there is merit in the answer which was flagged as VLQ, i.e. the post can be edited to be better, then that invalidates the claim that the post is VLQ and the flag can be declined on that basis. While we mostly mark other categories flags as helpful if we see the intent of the flagger, we are quite conscious about marking VLQ flags as helpful because it carries an auto-downvote and the mod who handles the flag may think the post does not deserve one.

We decline VLQ flags because they are ambiguous in nature and we want to discourage people from using it. Unlike other flags which have some sort of a procedural approach, VLQ flags are subject to discretion of the handling mod and as such, you might get different results. Now you understand why we hate this type of flag.

Takeaway from this would be: if a post can be edited or commented or voted upon, let's not flag it as VLQ.
