Linux kernel developers discuss dropping x32 support

It was just several years ago that the open-source ecosystem began supporting the x32 ABI, but already kernel developers are talking of potentially deprecating the support and for it to be ultimately removed.
The Linux x32 ABI as a reminder requires x86_64 processors and is engineered to support the modern x86_64 features but with using 32-bit pointers rather than 64-bit pointers. The x32 ABI allows for making use of the additional registers and other features of x86_64 but with just 32-bit pointers in order to provide faster performance when 64-bit pointers are unnecessary.
This headline confused me for a second, because at first I thought the Linux team was removing 32 bit support - which obviously made little sense to me. As the quoted blurb explains, that's not the case.
