Yes and no, so to speak. My dearly bought Thinkbook has it. Any Asus of any price-range. Most HPs made in recent years. Literally anything in a slim form-factor will have this solution with the keyboard being plastic-welded to the top chassis.

Ironically, a lot of the actual consumer-grade shit, like Lenovo Yoga, etc., inherited their design from the old elephant euthanasia brick devices, and have detachable keyboard modules. But it is actually glued and fused to what is doubling as the back panel for the mainboard. Which is also the solution on many of the older IBM-ish Lenovos. The keyboard module itself is not difficult to produce or replace on these devices, and is just attached with a standard ribbon cable. But to actually replace it requires some form of OEM-specific voodoo.

I am told by entirely reliable industry insiders that this is not done to make sure the laptops must be specified to different regions, to maintain these artificial region-offices of these companies, at all. Or that it is one of the few remaining things that can be glued to the laptop, so that when it breaks, the whole thing has to be replaced - meaning that it is a great way to make sure random consumers also buy warranty "deals". I'm told none of these things are involved, at all.
