I've got another trick to use in place of a Magsafe type cable. Get a cable that is a few feet longer than you need, and attach a couple magnets a few feet apart on the cable. Then click the magnets together. Now you have a cable with a loop that is held closed by the magnets. If someone trips over the cable, the magnets come apart and pull out slack from that loop, instead of pulling the cord on the back of the laptop.

Not quite as good as having the cord detach, but it still helps in the majority of minor trip-induced cord pulls (depending on how much clack in the cable you leave bundled between the two magnets).

Are you selling this on Instagram? I just got an ad in my feed for a product that does that

No, I was thinking of designing and 3D-printing a magnet holder clip -- didn't realize someone else thought of it too. I guess what they say is true, there is no unique new ideas.

Is what you saw just a couple clip on magnets (like what I was thinking), or is it a two-piece cord held together by magnets (like the previous comment mentioned)? That would be cool if someone already makes this as a product.

The product was a full integrated cable. I won't buy it for that reason as I would 1) like to retrofit my existing cables and 2) be able to choose the cable for the spec of the cable itself. If you made a clip and magnet for retrofitting on existing cables I would buy it if it was offered for a reasonable price.

Anecdotally, I’ve been using one of these (different brand but looks exactly the same) with zero issues between a Thinkpad X1 and a USB-C hub. It’s extremely convenient to be able to attach everything (PD, HDMI, USB) from a single cable that’s literally touchless. The magnet and positioning allows it to automatically connect when I set the laptop on my desk, and to use the laptop elsewhere I just pick it up and carry it away. Much better than a floppy MagSafe that only does power.

If you look into those magnetic things a little bit you'll notice they don't support full thunderbolt data rates. It’s largely physics that’s holding us up, not necessarily Apple. In theory data rates don’t matter strictly for charging but then we’d be back at a different cable/port for charging vs data transfer which would be subpar UX. If nothing else I think it’s why you only see these things aftermarket. I do share your sentiment, though.

It seems to depend on what you use them for.

In my experience, they're good for power. Driving a 2.5k monitor over DisplayPort works reasonably well if the computer is on a solid surface (not your lap).

But they don't work well for 4k video (especially with a direct HDMI adapter) or USB 3.0 data.

I purchased that. It doesn't suck. Though, I bet Apple could do better if it were integrated.

I've been using that exact adapter for several months now and I'm pretty happy with it. Carries power and data for my home setup + I have a separate one just for power for my mobile setup. What were your coworkers' complaints about it?
