It depends where your benchmark is. Writing a browser that passes acid tests and supports all the standards (old and new) as well as the sites that aren’t standards compliant but users might still expect it to work; that is an insane hard task. But building a console browser that supports a subset of standards and has no Javascript support is a much easier job (read: “easier” as in relative to the former task). Much like building a kernel + CLI shell is easier than building a fully multi-tasking OS with GPU accelerated GUI compositing, stable ABIs, modular driver model, and full support for 99% of common hardware.
