I would want to be able to use native code though (with all of the access that is possible with native code); of course such native code extensions would not be possible to add to a spreadsheet file and you must add them to a configuration file instead (both for security and to avoid unportability).
(It does not necessarily mean that WASM is not also possible. If it is, then some kinds of native extensions might be possible to convert to WASM if you want the portability and security that it involves.)
