Thanks. You can certainly bake into the alpha channel, you just need to be using a file format that supports an alpha channel AND set the output to RGBA. If those are true, then you will see a new socket appear on the output node called Alpha which you can pipe what ever you want in the alpha channel into. Do keep in mind that file formats may use a different color space for the alpha data, for example .png uses sRGB for the main channels but linear for the alpha.
