Is there any chance of adding a "strike through" tag to the available options?

I know this would mean work for someone.

It's to do with the tone of a message. I [strikethrough]always[/strikethrough] sometimes feel that a struck-out word can help to make a message better by inserting that pause that we posess in FTF dialogue.

It's not a big deal, perhaps good enough to be put on a to-do list "next time I'm maintaining the panel"?
