Ultimately, pursuing a full-featured graphical web browser might not be the right approach for a volunteer-/hobby-driven project to develop a web browser. But it would absolutely make sense that a newly implemented terminal-based browser in Go (or any other memory-safe language) could/should replace Lynx and w3m.
It's actually pretty surprising that there hasn't been a niche surge in websites specifically meant to work well in textmode browsers, considering how many programmers claim to spend 90% of their time inside either a terminal window or in a web browser. Even now on HN I'm typing this in Firefox. And Sourcehut, too is widely acclaimed for being "simple" and/or "minimal", but it's not exactly great (or even clear) to look at in the two browsers I just checked.
