> no DOM access meant the only viable use cases were compute-heavy workloads like codecs and crypto,

no, it didn't mean that, because the overhead is not a deal breaker:

1) you don't have to do the glue code (libs can do it for you)

2) there's overhead due to glue, but the overhead is so small that WASM web frameworks easily can compete with fast JS frameworks in DOM heavy scenarios.
