Goal of SMT isn't double the performance, it having >1 threads better using execution units within a CPU core.
The example frequently given is running an integer heavy and floating point heavy code at the same time - they don't use the same execution units, so they can better utilize available resources.
In the real world it's more likely that one thread is waiting on memory access or some other part of the system and the other thread can proceed during that wait.
I'm unsure of the security of simultaneous multithreading on modern x86 CPUs

Not to excuse NPM and the entire "broken in new ways every time you look at it" javascript ecosystem, but any installation system that can run arbitrary scripts/commands as a part of the install has this same problem.
This anti-feature should be removed, and other safer workarounds provided.
A SSH Certificate Authority signing host keys handles that, but requires additional setup.
