I never much got into the digital teleconverter concept, myself. Why not use a real TC and just crop the image down, instead?

This was taken with the 50-200mm and 1.4x TC, and given about a 50% crop. Advantage? No digital interpolation to mess with the actual pixel level information.

A real TC will almost always result in a better image, but the problem with a real TC is you have to first have one and you also have to attach it. Digital teleconverter (or Digital Zoom in Panasonic cameras) comes free with the camera and is a button away.

Kind of off topic, but I wish camera manufacturers can try some of the super resolution modes like Google Pixel does. It's similar to but not quite as demanding as HHHR. By using this only tied to digital zoom, it allows the camera to ignore the unused parts of the sensor area and get a faster burst of images.

Absent of this, having a continuously variable digital zoom would be useful. My Panasonic only comes with 2x or 4x. 4x is a bit too much, 2x works ok, but it would be much nicer to be able to get other values (even less than 2x). For example, if I want something between 140-280mm (on my 14-140mm), the current digital zoom implementation means I'm unnecessarily throwing away 3/4 of my sensor area to achieve that.
