Now that we're getting rid of the "--dev" flag, how would I run a persistent local process? Something like this:

kind: Module
name: local
type: exec
local: true
include: []

services:
  - name: local
    deployCommand: []
    devMode:
      command: ["npm", "run", "dev"]

(I know that's a module, just copied from existing config, but I figure it'll work the same with actions.) Previously I'd just run

garden deploy --dev

, and that deploys the stack, starts sync mode were applicable, and starts the local process. Or specifically

garden deploy local --dev

Should the

--sync

flag be used here since obviously there's no sync going on? Or do we need to add special primitives around local processes (which is really not ideal imo)?
