I know there is a topic about the solution-verification tag (vs proof-writing), but now we have the proof-verification tag which has affiliated 2452 questions, while "solution-verification" has only 540. Why we need both of them?
There is an objective distinction between proof-based mathematics courses, where students write proofs, and non-proof-based ones, where they write solutions to exercises following given algorithms. In both kinds of courses a student might want feedback on their work. The nature of feedback is a bit different, and so is the set of users qualified and willing to give such feedback.
For example, engineering students who excel in Calculus and Differential Equations may be quite good in answering solution-verification questions, while having no interest in proof-verification. It makes sense to have both tags in place, allowing users to filter questions according to their preferences.
While there could be some meaningful distinction (in theory) this does not seem to work well in practice. I checked a bit manually, and also observed that 150 questions (this are almost 20 percent) of the questions tagged solution-verfication contain the word "prove" (and rather not in the way "I do not need to prove this I just need the solution").
To monitor the tag(s) and to enforce compliance seems unnecessary busy-work given that the gain from it seems marginal. I thus reiterate the proposal to create a synonym.
