Yes there is much to be said for PD. I mention it purely to facilitate budget conscious entry:

Pinecil + existing brick: 26 USD

Pinecil + Gan charger: 50ish on a good day

Plus headroom - the old charger I've got is 120W rated.

For most people your suggestion makes more sense, but I'd like to spread awareness of the alternative too. Saves money. Saves ewaste.
