The ability to request an update via the app has been around for several weeks (or months?). It's not a direct request to the servers...but if you use the app to Schedule Service, one of the options is Firmware Update. That request is then sent to Tesla Virtual Service and they can push the update.Elon tweeted at one time that this would be a good idea (request via app) but don't know if it's on his radar to actually do it.
