How strange that they didn't do that earlier.
There is a good reason not to do this.
No Lightning wallet software developer has released their client. As of today, pre-release development and testing is still underway for all Lightning developers. Anyone using Lightning payments today is taking a significant risk that they will lose money.
No money has been reported lost as a part of testing the Lightning protocol, but that doesn't mean that there are no flaws in the software that could let that happen.
I'll be very happy when Lightning is up and running, but using pre-release software with real money is reckless. This is premature.
