Sure, and a lot of tools will do this in one way or another. Either instrument code directly or provide annotations/macros to trace a specific method (something like tokio-tracing in the Rust ecosystem).

However, tracing literally every method call would probably be prohibitively expensive so typically you have either:

1. Instrumentation with "understands" common frameworks/libraries and knows what to instrument (eg request handlers in web frameworks)

2. Full opt-in. They make it easy to add a trace for a method invocation with a simple annotation but nothing gets instrumented by default
