Often when people post their solutions to a particular problem on a question of theirs and they tag it solution-verification, the solution that they give is flawless, or can be improved a small amount eg by cutting down on unnecessary assumptions.
In these cases, there isn't much that you can do to answer the actual question: you can just post a comment saying "Yes, your solution is correct. Perhaps it could be improved slightly by...".
However, what I often see in these sorts of scenarios is that people then post answers to the question offering alternative solutions, although the OP doesn't ask for one. This often is very useful to the OP, as can be seen in the numerous instances when the OP thanks the answerer profusely for giving them a new method in their toolkit. I've done this myself sometimes.
So, here's my question:
Should we be answering questions tagged solution-verification with alternative solutions when the OP doesn't don't ask for one and the argument that they give is fine? What is MSE's policy about this?
