That's a Universal Argument: if someone names a feature, you have two outs. Either Gmail has it, or it's "specialized".

Here's one feature my email client has: automatic spell-check, such that emails are disallowed from being sent if they have any spelling errors (with an override, of course). Gmail has a manual-trigger spell-check, while the browser has automatic spell-checking, but neither have a personal (jargon-customized) dictionary built up over decades nor an automatic modal dialog if the message to be sent has a mistake.

I guess automatic spellcheck override dialogs are specialized, eh?
