It is a lot of work.
While for crypto-escrow you can just do a simple multi-sig with a hot keys that running on admin machines and they sign results there and they couldn't get the money, so no reason to try to hack the system.
Much easier setup.
Moving from the second to the first is very trivial - just make it based on distributed consensus of nodes that are run by separate entities, may be even several different cloud vendors.
AWS also doesn't have some interesting things from crypto-world - smart contracts, that are just like lambda functions that couldn't be altered in any way and could be trusted by third-party. They have Nitro Enclaves, this is close, but quite hard to use.
For example, go can handle about the same amounts (be advised that this tests are for 4 cores, so results have to be divided): https://github.com/smallnest/go-web-framework-benchmark
Performance is a very important thing in js world for a peace of mind of devs.
