Whether or not this is as good as brand-new software that managed the layout itself is debatable, and nobody will write that software anyway because they won't have users that have SSDs that let the database manage the disk in full.
Maybe it's not relevant to databases, but in my experience everything written with SSDs in mind has been horrifying. Compare two machines with nice NVMe drives running Windows 10/11 and Windows 7. Your user experience will be virtually identical. Swap the SSDs out for hard drives. The Windows 7 machine will get slower and have the many split-second delays we all remember from back in the day. The Windows 11 machine, however, will completely shit the bed. Massive multi-second delays crop up trying to do the most simple tasks.
So far developers, instead of taking advantage of SSDs, are just using them as a crutch.
Many companies refuse to test their software on low-end hardware, because effort. I've seen testers test software, get annoyed at how slow it was, and instead of letting that be a test result they just switched to a faster machine.
