No but it might be fun to play with in a Qubes environment or similar where you can inspect packets going in and out for anything weird happening.

Looking at packets will only get you so far if they're encrypted.

Software like this has way too many opportunities to exfiltrate information for that approach to work.

That's true, but if it is trying to exfiltrate data you will probably see more packets coming out than going in. If the concern is that the SSL cert they add allows them to decrypt your data, and you see it sending your requests anywhere it shouldn't, you'll get a window into what they are trying to do. It's not perfect, but it is possible to gain information in such a way.
