XMPP is just the internet standard, it does not try to solve the network effect problem. But it would be important if platforms like Signal, Telegram or Matrix would adopt it instead of inventing their own incompatible protocols. Without a internet standard for IM we cannot hope for advanced features like usable federation, encrypted messaging or A/V calls between platforms. We probably should not be promoting platforms which are not standards compliant.
