You can always just select stuff with your mouse and press the delete key. We're writing code, not prose, here. When was the last time you used paragraphs anyway?
Replace "paragraph" with "surround" (vim-surround), "argument" (argtextobj) or "indent" (vim-indent-object) then, which compose brilliantly with (c)hange/(d)elete + count + (i)nside/(a)round.
When writing documentation. The mouse + delete is not as easy when you're doing non-trivial movements, such as "replace everything between these matching parenthesis"
