DynamicSupervisor traps exit signals and handles ones coming from its children:

https://github.com/elixir-lang/elixir/blob/427d21e410d1846c232d0a0b0e87cce629884dfa/lib/elixir/lib/dynamic_supervisor.ex#L795-L801

However, it also implicitly ignores exit signals from non-child processes: elixir/lib/elixir/lib/dynamic_supervisor.ex at 427d21e410d1846c232d0a0b0e87cce629884dfa · elixir-lang/elixir · GitHub

Does anyone know - is it an intentional design decision?

I’m trying to link it to a process that’s not its direct parent/child, so it would exit when the other process exits, but of course at the moment it doesn’t work. I don’t care so much about my use-case per-se (I can figure out a solution), but I’m in general wondering if there’s a good reason for how DynamicSupervisor is implemented - i.e. maybe I’m doing something that goes against first principles?
