maybe this is a knee-jerk reaction but I don't see any good reason for this. At it's core Google's job is to take an input and list outputs. The marketshare of people using lynx is small enough that whatever advertising or ai extras they want to squeeze in won't be meaningfully impacted by not working on lynx.
Standard Google page can use JS and WASM to fingerprint device and detect bots. No-JS page cannot detect bots so it makes sense to shut it down to prevent using it for bot detection bypass.
