That’s a goofy design choice.
The standard is capable of 240w

Pretty much every modern laptop runs on 20v internally so USB Cs 100w was super easy to switch to. To get 240w you need to intake 48v and then convert that down to the 20v ish that laptops crave.
The framework 16 is the only laptop I know of that runs on the new spec. MacBooks will do 140w via MagSafe, and the new ThinkPad P1 does it over actual USB C. But almost nothing uses the new spec yet. Given more time I’m sure it will be more popular.

Only in the latest USB revisions, which are fairly recent

You got me curious, looks like it became a standard in 2021. Pretty old for a performance laptop but I’d imagine that it took awhile for the manufacturers to catch up. Thanks
