alt Hacker Newshttps://github.com/WebAssembly/custom-page-sizes is a proposal championed by my colleague to add single byte granularity to Wasm page sizes, motivated by embedded systems and many other use cases where 64kb is excessive. It is implemented in wasmtime, and a Firefox implementation is in progress.

If it has less than 64 kB of memory how is it going to run a WASM runtime anyway?
And even cheap microcontrollers tend to have more than 64 kB of memory these days. Doesn't not seem remotely worth the complexity.
