Is a "language" developing to trigger bots?

The same way that we are now all used to @somebody to message / tag them or #hashtag a topic to make it searchable?

For example:

• There is the u/RemindMeBot triggered by RemindMe! that has the !exclaimationmark
• DuckDuckGo? has its !bangs that jump you straight to content when they are used. Though that's more a shortcut.
