Is Intel-PT over-engineered and not really needed in practice?

Looks beautiful so congratulation for the launch.
Not sure if today this is enough though without any kind of AI chat assistant. Trae [0] is based on VSCode and Jetbrains Fleet are good looking as well. Visualization is definitely a big plus but there is also alternative like using rerun [1] and dearpygui [2] or some VSCode plugins (Python Image Preview, AREPL for Python)- might be hard to compete with those free alternatives on a subscription model IMHO but good luck!
