I don't really like the spoiler headers. And someone new to the site may see those and come to the conclusion that there's no point in clicking on spoilers since they only change color...

Not an issue though. Wiki pages can be locked and we really should lock the site related wikis. And even if someone did change it, wiki's have a revision history.
