Charging for five hours isn't particularly attractive to save resources on a $20 charger. However if you had more expensive smarter chargers in the first instance that could have firmware updates and more repairability, then you'd avoid the need to update (e.g. the first 100W usb power delivery standard was agreed almost a decade ago).
I do wish phones were more repairable though - I've accidentally cracked a replacement screen and stabbed a battery in the past when replacing broken bits on my phone.
