No, but it's likely going to be much sooner for 1-style addresses (the only kind currently which support signed messages / proof you're the recipient).

Supporting others need BIP 322 to be completed (I may need to help out to get it past finish) and/or accounts of some sort 

 Got it. Hope it’s gonna happen this year 🤞 

 P.S. for some reasons I can’t zap you 🤷‍♂️ 

 I have no idea why not
