BT download and PCDN would create tons of connections, and might be easily to reach the 8192 limit, one of my friend sees 50000+ links when hosting PCDN.
I don't know what PCDN is, but what we care about in Linux is whether the change under Fixes introduced a regression. Optimizations, and improvements no matter how trivial in terms of code are not fixes. So did ba37b7caf1ed ("net: ethernet: mtk_eth_soc: add support for initializing the PPE") make things worse. And if you're saying there are 50k "links" in real world why is 16k a major win? it's 1/3rd of the total.
