How to animate Particle System properties in 5.x via Animation Clip

In Unity 5 (I’m on 5.3.1p2), many of the Particle System properties that were previously exposed and could be animated in Unity 4 are no longer adding curves when modified in record mode, nor are listed in the Add Property option of the Animation view.

For example, how do I animate a Particle System’s Start Size property from an Animation Clip? Note that this is distinct from animating the particle size over lifetime of the particle. Rather, I want a clip to change this property of the system during an appropriate Animation Controller state.

I’m trying to find a convenient way to fix previously working Unity 4 Particle Systems in a Unity 5 context.

I ended up just making a custom component that exposes the fields and animating them indirectly.
