Yes but I've yet to see a website use more than 10 simultaneous websocket connections, let alone 1000.

There's something like a 256 count limit on total websockets, and 30 per domain, in Chromium.
A malicious website could open up 256 websockets and as many HTTP connections as the browser allows, and that might be enough to swamp cheaper NATs.
See https://bugs.chromium.org/p/chromium/issues/detail?id=12066 for some 2009 discussion about people having troubles using the web when background tabs held connections open for polling. That wasn't a NAT issue, but it does highlight that a decade or two ago we all thought we only needed to manage tens of connections for a host to be online but that rapidly spiralled into hundreds.
