I think the idea of traditional exchanges adding features from DEXs is quite interesting. It's like combining the best of both worlds. CEXs can become more versatile and user-friendly by offering DEX-like features. IMO, this would make trading cryptocurrencies easier for everyone.
I'm not sure about it but what I know is the centralized exchanges are almost hitting their limits there's nothing they can do anymore, the reason why they're still the center of attention is due to the new entries in the industry and the only cheap option, but when it comes to the transparency & security they really cant offer better than this.
No doubt their overall user experience is far more developed compared to the DEX's but what DEX's are offering is far more superior to the centralized excnages, I'm sure in near future with the network fees solution ther'e gonna lead the way.
