But do modern DL approaches (e.g. SQuad, translation models) defy this approach? They train DL models on labeled data without knowing anything about syntax trees, and allow NN do all the magic..

Sure, but that doesn't mean that knowing about syntax won't improve the result. If you're training a translation model on a huge database of labeled examples, it might discover syntactic relationships from scratch. But if you don't have so much data, you're probably better off using all the auxiliary information you can get.
this is likely correct, additional high quality input will likely improve performance, but creating such input for 200 modern human languages requires significant effort, much larger than allowing NN to solve this problem, that's why researchers invest this effort into NN improvement, not syntax tree creation tooling.
edit: clarification
even if just another half of results are proven to outperform traditional approaches, is it strong enough trend?
