It seems like it might make sense to just change the ComponentEncoder default?

Ref bytecodealliance/wit-bindgen#1622 (which combined with this made for a very confusing debug session 😅)

Sorry for the confusion!

The intended default here is disabled-by-default as it speeds up linking a bit, so I'm going to fix the docs in #98
