Description
Right now the synchronous new WebAssembly.Module(foo) / new WebAssembly.Instance(foo, bar) functions have a 4 KB size limit on the main thread, because they block the event loop.
However, you can use them in regular workers without the 4 KB limit.
Should they be allowed in service workers with or without the 4 KB limit?

Research direction
Start by reading the Service Worker specification sections governing WebAssembly and synchronous execution, then compare the stated 4 KB behavior in the main thread with regular workers. The work is done when the service-worker behavior and any size limit are decided and reflected in the specification.
