LGTM1
This doesn't show up in our chromestatus UI. Have you sent if for
"shipping" there? If no further comments arrive, it may be that it has
fallen off our radar because of that.

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.

Risks
Interoperability and Compatibility
/Gecko/: Shipped/Shipping
/WebKit/: Shipped/Shipping
/Web developers/: Strongly positive We received repeated bug reports
because of 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).
