It’s a trade-off - they COULD build a laptop which can run everything at 100% 24/7 indefinitely, but it’d be heavier and more expensive, with zero benefits to their target audience of "people who only run at 100% for a few hours per day"
If there was any added weight it would be with the charger, not the laptop so... Incredibly unlikely.
It's way more likely that Apple just didn't design the connector to be able to deliver that amount of power. So they'd have to add a second one or switch connectors/design a new one.
Both would be suboptimal as well.
That’s what I’m talking about too

Whether it’s charger or laptop, that’s still more weight that the end-user needs to carry around in their backpack, which 99.9% of them won’t need
Only too-clever-for-their-own-good-designers like automagic things. No user does.
