The current Arduino IDE version (2.3.8) is much better, smoother, stable, and more performant than the 2.0.X version often referred to in the documentation. In particular, it supports symbolic debugging, which is widely used by the ESP and ARM communities (and even by the Arduino team itself). There was no such thing for AVR chips, because the existing open-source GDB server implementations did not offer themselves as easy-to-install cross-platform solutions. In fact, for the modern parts, there used to be no cross-platform solution at all.
PyAvrOCD is such a solution and it is ready to be integrated into megaTinyCore with this PR: #1275 (comment)
