The disk 'Format' dialog in Windows was only meant to be a temporary solution but it's still chugging along, 30 years later
Just imagine that you're a software developer and you've got an enormous list of tasks to do. One of them happens to be creating an interface for the formatting of storage drives, so you'd probably just knock something together, just so it can be tested and ensure it all works. You'd maybe even think that it would all get tidied up and made pretty for the final release. What you wouldn't expect is that it would remain as is and carry being used for 30 years, totally unchanged.
