This feature request is for a specific type of drilling operation to be added to the Easel software itself. That doesn't mean that the X-Carve, or other CNCs for that matter won't do the job you are looking to do.
I personally have used my X-Carve to make many 3/16 holes and a CNC is definitely the way to go when you have to line up those holes in a pattern or grid. Easel and the X-Carve can make these holes, but through different methods. An example would be to use a 1/16 end mill and have it mill out a 3/16 hole, but that isn't to say that drilling operations aren't possible. If I have a drill bit that I just want the machine to plunge over and over in a grid into a piece of material, I usually go into Fusion 360 (free for the hobbyist) and use it's excellent CAM drilling operations and then import the F360 g-code into Easel, hit carve and away it goes.
I'm not necessarily trying to sell you on the X-Carve (I am partial to it), but the X-Carve can definitely do the job you are describing... hope this helps.
