Defaults matter. If you are like myself in that 99.9% of the time you want to paste plain text, having that be the default is more useful than having to do a three-key chord.

Why not just use the Paste and Match Style menu item or ⌥⇧⌘V?

- This app can make it the default behavior. - That menu item is not available in all apps. - The keyboard shortcut is hard to remember and type. - In some apps, like Chrome, the keyboard shortcut is different. - This app can exclude certain apps, preserve links, and also remove tracking parameters from URLs.

Let's be honest, with most people Ctrl+v/Cmd+v is more ingrained in their muscle memory than the longer keystroke combo. More than a few time each week I find myself silently cursing myself for not pasting as plain text.
