There is always netbsd, which prioritizes portability.
Whether you like it or not, linux is a commercial operating system primarily designed and built by people working for commercial entities, to solve commercial problems.
Nobody in the commercial world is running 486, and supporting old CPUs makes it harder to maintain and build features for modern hardware that commercial entities use.

It looks like NetBSD and FreeDOS are the last major operating systems that support 486s. Even OpenBSD and Minix require at least a Pentium processor.

Title is slightly misleading, it is not leaving behind 486 types of CPUs individually, but the "486 CPU".

Absolutely nobody was confused by this.

I feel like at this point they could’ve waited more years just for bragging rights.
(I don’t mean to say 18 years is not brag worthy, but 20 rolls off the tongue better.)

Well, actually... The LTS kernel with longest support before 6.15 is 6.1. It will be supported until December 2027 [1] which is a few months over 20 years after the last 486 CPU [2].
