For time travel debugging in Go:
The Delve debugger for Go supports debugging rr traces: https://github.com/go-delve/delve/blob/master/Documentation/...
Undo (who I work for) maintain a fork that debugs our LiveRecorder recordings: https://docs.undo.io/GoDelve.html
Either rr (https://rr-project.org/) or our UDB debugger (https://undo.io/solutions/products/udb/) can do some time travel debugging of Go programs via GDB's built-in support for Go. I believe its weakness is in support for goroutines, since they don't map well onto its idea of how programs run.

This is another example, a tracing time travel debugger for Clojure https://github.com/jpmonettas/flow-storm-debugger
Supports a bunch of stuff described there and more.

> Debuggers need to do more things
It's true that coming up with an interface for an abstract debugger is harder, but it's not impossible. Microsoft create Debug Adapter Protocol (https://microsoft.github.io/debug-adapter-protocol/), which is conceptually similar for LSP. It's not perfect, but covers most basic operations pretty well, while leaving to the debugger to deal with the implementation details.

watchpoints
watchpoints is an easy-to-use, intuitive variable/object monitor tool for python that behaves similar to watchpoints in gdb.
It's sad that Python does not really support some of these debugging methods.
E.g. you cannot really watch variable changes. There are some workarounds, like writing a custom __setattr__ or __setattribute__ in case of an object, or checking all STORE_* operations. https://youtrack.jetbrains.com/issue/PY-30387 https://github.com/gaogaotiantian/watchpoints
Reverse debugging is also sth I would like to have, and there are a few projects to support this, but it's not really well supported in standard CPython. https://foss.heptapod.net/pypy/revdb https://pytrace.com/

* Aha! In digging up the docs for NDC, I found this[1], which does mention a book for your reading list: "Patterns for Logging Diagnostic Messages" part of the book "Pattern Languages of Program Design 3" edited by Martin et al.
