I am using PM2 for local development of a moti instance, so I need to use 3 commands:

    "pm2:dev": "dotenvx run -- pm2 start ecosystem.config.js",
    "pm2:logs": "pm2 logs",
    "pm2:delete": "pm2 delete ecosystem.config.js",

Start with pm2:dev & pm2:logs

End with pm2:delete

So that's why I think having a clean-up process would be great.

From what I understand, I don't believe the daemon will have any effect on the workflow you're describing.

Did you give it a try? I'd be interested to learn if you found any unwanted behaviors.
