I think you're unfairly blaming weight training for the effect of cessation of skill training.
When, due to injury, I became unable last year to perform either the snatch or the clean and jerk, I was relegated to being able to do whatever it is I could. Lots of less complicated exercises that don't share any patterns in common with either of those two lifts.
At a recent experimental trial of my technique after 15 months away from the two lifts, it came as no surprise that I came kinda bad at them now.
Do I blame the other weight training? No: I realise that these two lifts require constant practice to remain smooth, precise and efficient. It's the same for other inter-muscular coordination tasks. If you stop doing them, you get worse at them.
