Cross posting https://github.com/WebAssembly/custom-page-sizes/issues/25 in this PR for wider CG visibility, since I know there are some folks who are interested in addressing these use cases but who haven't necessarily been watching the proposal's repo and can therefore miss notifications:
Precise and complete overview document is available in a forked repo around which a reasonably high level of consensus exists.
Updates to the actual spec document, test suite, and reference interpreter are NOT yet required.
If anyone believes that that there exists a better design for supporting smaller-than-64KiB memories, that an alternative approach hasn't received enough consideration, etc... please speak up well before then! Feel free to leave a comment here, open an issue in this repo, or reach out to me privately.
