I wouldn't be too worried about the atrophy. Or at least not much more than you already were: you get the same atrophy effect just from IDEs and compiler errors and warnings.
To give a concrete example: I'm pretty good at doing Python coding on a whiteboard, because that's what I practiced for job interviews, and when I first learned Python I used Vim without setting up any Python integration.
I'm pretty terrible at doing Rust on a whiteboard, because I only learned it when I had a decent IDE and later even AI support.
Nevertheless, I don't think I'm a better programmer in Python.
