Ping @okonet do you have any opinion on reducing the number of dependencies? This Draft MR is a trial on whether current fresh Node.js LTS versions would allow us to drop execa and just directly use spawn(). Looks like there's plenty of improvements and the syntax is quite nice.

Hoping that Windows tests pass.... 🤞

[okonet]

I'm fine with it. Looks nice indeed. Why are user tasks need still to be wrapped with execa? Can they use this wrapper? Or did I misunderstand this part?

[iiroj]

This was easier to test with, thus the draft PR. For user tasks it will still need:

• shell support
• support for aborting, possibly with a signal
• some refactoring because current code passes the execa result object around (mostly unnecessary)

[okonet]

That makes sense. I'm wondering if it then worth the change if we keep the dependency in place.

Can these missing bits be done just with Node?

[iiroj]

Should be possible. I'll keep this as a draft until it's done.
