Grease Pencil - trying to draw with auto-keyframe turned off should add a frame if there are no frames

I like the recently-introduced feature of Grease Pencil that it only adds new frames when auto-keyframe is turned on. Very useful.

However, it causes a problem - many people have auto-keyframe off by default, and in that case, when you add a blank grease pencil object and switch to draw, nothing happens. You get a rather cryptic warning in the status bar ( No available frame for creating stroke ) but basically it 'feels' like it's not working. The only way to draw is to turn on autokeyframe, draw, then turn it off again.

Seems like quite a few people have this problem, I certainly do! devtalk.blender.org/t/grease-pencil-no-available-frame-for-creating-stroke/18114

Why not make an exception to the rule - if there's no keyframes on a GP object, and you start drawing, Blender adds a keyframe.

I mean, when you start drawing you always want to draw, right? As far as I can see, there's never a situation where you'd start drawing on a blank grease pencil object and not want to add a frame?
