Here is an edit suggestion which adds a sed tag to a question: https://unix.stackexchange.com/review/suggested-edits/177179
This question does not mention
sed anywhere and originally only had the awk tag and mentioned OP's attempt in
awk. The only thing related to
sed is the answer with the most votes.
So is this OK? According to Shall tags refer to the solution, too? it would be. But in this case it might also be better to remove both the awk and sed tags since OP might very likely not mind, making the question not specific to either? And maybe adding the text-processing instead?
It's also worth noting that there is the following canned edit dismissal text:
This edit introduces tags that do not help to define the topic of the question. Tags should help to describe what the question is about, not just what it contains.
