"Not an answer" answers are often quickly flagged for mods to deal with, and that works fine.
The "trusted user" privilege appears to exist largely to alleviate some of the load from the mods, by allowing users to vote on more things, for example deleting answers because they are "not answers".
Currently, besides the mods, there's only two users with this privilege though. My guess is, this means we can't actually use the vote system, yet, for this purpose.
So does me using it make any sense?
You are correct: We don't have enough users with the privilege of voting to delete a post, to avoid diamond moderators chime in to delete a post.
It could seem that voting to delete a post doesn't have the effect of taking out the burden from moderators, but it is not so. The alternative would be, for example, flagging an answer as not an answer. This would make the moderators check out if the answer is a comment, another question, or just thanks for a given answer. Contrary, your vote to delete a post is explicitly telling the moderators that you think the post is bad enough to be delete. Plus, since you are a 20K user, I trust you know the difference between a wrong answer, and something else written as answer.
So, definitively, your votes to delete posts are welcome, as they do help the moderators.
