SpecificationNone Summary There exists a limit on the size of a module that can be compiled with `new WebAssembly.Module()` on the main thread. This limit is 4KB, and it was introduced when WebAssembly modules got compiled eagerly with an optimizing compiler, which could block the main thread for many seconds and even minutes. In the meantime V8 launched lazy compilation for WebAssembly modules, and the execution time of `new WebAssembly.Module()` is below 1 second even for the biggest modules we see, even on the weakest devices we measured. Therefore it is time to remove this limit.

Especially for tests synchronous compilation with `new WebAssembly.Module()` is useful, but the size limit prevents bigger tests from using synchronous compilation. *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Debuggability Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?No Flag name Requires code in //chrome?False Estimated milestones Shipping on desktop 114 Shipping on Android 114 Shipping on WebView 114 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
