You can't make an open source HDMI 2.1 driver

I think the connector good be better in terms of reversibility and none of that weird locking it has but it's an incredible technical achievement. And it seems perpetually ahead of HDMI in terms of features and Bandwidth.

Not for the past few years. Although DP 2.0 has been 'released', there are no products actually shipping with it, and in practice DP 1.4 is the latest standard. DP 1.4 can't transmit 3840×2160 at 4:4:4 144 Hz without Display Stream Compression (DSC). HDMI 2.0 can.

Here's a GPU with DisplayPort 2.1 https://www.mindfactory.de/product_info.php/16GB-Sapphire-Ra...

Here's a Display with DisplayPort 2.1 and higher Resolution&Refresh Rate than you specified https://www.mindfactory.de/product_info.php/57Zoll--144-78cm...

That monitor was released not three months ago; I was describing the 99.99999% case. DP 2.0 is rare enough that an article[1] was produced this year about its scarcity.

Is there a point for a monitor to use DP 2.0 when the only formats it can display are all supported by 1.4?

And there is DP-Alt for USB Type-C, which makes it much nicer than a regular DP connector.

Locking is a feature, not a bug

Locking in general yes, the specific implementation of locks on the DP Plug are annoying.

Especially when your monitor falls down from your desk instead of simply disconnecting at the plug.

Easily solved by proper cable management.
