I had similar issue. Every time I was writing a systemd file, I would have forgotten what I previously learned.
These days I just make deepseek/changpt do it. 90% of the time they get it right. Even if they get it wrong, you end up with a file that will be perfect with a line or two changes.
I agree with everything you said about jetbrains. Their vs code like push and AI push has degraded their quality.
