A Delete tag, such as I added to pages, is a minimally intrusive and easily reversible action. You demonstrated that yourself. Undoing a Merge done through editing is a more complicated matter for whoever comes to fix it: what to save, what to remove, what to redistribute, etc. It's more of a hassle for the clean-up crew.
