北青谈新赛季准入：梯队建设减量意在减负，对欠薪仍零容忍（北青：新赛季准入压缩梯队以减负，欠薪仍零容忍）

Considering league requirements

I'm thinking about the recent changes to youth football league requirements, possibly simplifying from having U21, U19, U17, U15, and U13 teams to just U21/U19 and U17/U15. There's also a connection with how clubs' youth qualification results affect their league access. However, I have to be cautious about hallucinating details. I should ask the user if they want a summary, key points, or a brief news outline. I can provide key takeaways about implications and the term "减量." I'm also ready to draft a concise news note or social post if needed.
