From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux newb here. So I'm assuming this would make the kernel smaller, and take up less space. Would it be significant?
The Linux kernel is well over 30 million lines of code (lots of that is drivers).
This change shrinks the kernel by about 15,000 lines. That is not nothing, but it hardly moves the needle.
It is just one less thing to have to worry about and one less constraint to limit flexibility in the future.
It’s probably less about making the kernel smaller and more about security and reviewing code. The less code you have to maintain, the fewer vulnerabilities even if it’s old code.
I would doubt almost 20 year-old code is taking up a lot of space or presenting new vulnerabilities. And it’s obviously open source so if anyone needs it, they can always use an older kernel or maintain it. Sometimes, your oldest code is insane. I wish there was a budget for every company and government to pay retirees part time to go back over their oldest code that’s still in use. A lot of retired programmers would do it for fun and nostalgia. And to be horrified something they wrote 20 years ago hasn’t been updated or replaced.
There is no budget for it AFAICT but there is https://github.com/abandonware and others trying to help on that path.
Probably not a lot of space savings, but certainly a reduction in complexity, which helps programmers keep everything together and frees their time to work on the newer stuff
