I have collected 4 magsafe chargers from the various companies I've worked at because when I returned my laptop or got an extra, they never asked for the chargers back. It was very convenient, but now that I'm on the 2018 USB-C one, I have to throw all of them away via e-waste because I have literally no use for them.

You could try eBay or Craigslist for those.

Since Apple never licensed out MagSafe, the market has been full of poorly built counterfeits rather than anything from reputable manufacturers. That’s another thing I don’t miss.

Anyway, I’d bet there’s still some market for used MagSafe chargers to be used with older macs whose chargers have frayed.

there exist magsafe to usb3 converters.

Is it impossible to have a removable Magsafe cable?

Probably not, but Apple never made one.

The option we have now are magnetic breakaway USB-C nubs, but I've been hesitant to jump on that train because of stories about them breaking off in ports, short circuiting, or failing to connect properly. And especially if you have a 15" MBP with the 87W power brick, I don't think they can handle that amount of power.

Eventually I hope to see some well made versions of that from known good vendors, but even things like Griffin BreakSafe have crappy reviews right now.

Hah, the new Macbook laptop with only USB-C connectors: Slimmer and weights 2Kg less. But now you have to take with you 3kg of USB-C to everything (hdmi, mini-DP, USB-A, thunderbolt, ethernet, MicroSD, SD) adapters, each one costing you $15 at least. Oh, and this "feature" costs you $100 extra on the new MacBook laptop.

I hate Apple.
