The performance characteristics are attractive with incredibly fast cold starts and minimal memory overhead. But the practical limitation is language support. You cannot run arbitrary Python scripts in WASM today without compiling the Python interpreter itself to WASM along with all its C extensions. For sandboxing arbitrary code in arbitrary languages, WASM is not yet viable. For sandboxing code you control the toolchain for, it is excellent. I am, however, quite curious if there is a future for WASM in general-purpose sandboxing. Browsers have spent decades solving a similar problem of executing untrusted code safely, and porting those architectural learnings to backend infrastructure feels like a natural evolution.
The critical thing to understand is namespaces are visibility walls, not security boundaries. They prevent a process from seeing things outside its namespace. They do not prevent a process from exploiting the kernel that implements the namespace. The process still makes syscalls to the same host kernel. If there is a bug in the kernel’s handling of any syscall, the namespace boundary does not help.
