Tcl is deeply rooted in EDA and chip design industry, too many code were written with it. It's like C++, no matter how fancy/modern rust is, there is no way it's going to replace C++ for the next few decades. One way is to provide Python(python stdlib might be enough for simplicity) gradually, e.g. providing a Python binding for Tcl so for the future, you can write all new piece in Python, and it is either used directly or converted to Tcl behind-the-scene.
