curranty only trojan+tcp+tls/xtls has fallback ability you can't use fallback with vless/vmess

when using tls , having fallback is necessary to stay undetected from vpn server ,pass human/robot checks of tls website vision flow control is only available for vless-tcp-tls too , it's not an upgrade if you can't respond like an https website when opened in a browser
