Apple has made it clear they want to get rid of kexts tho

Correct. In terms of custom file systems, there are two paths forward: * For cloud-based storage — iCloud Drive and the like — you have File Provider extensions. <https://developer.apple.com/documentation/FileProvider> * For file systems specifically, you have FSKit extensions. <https://developer.apple.com/documentation/FSKit> This is currently limited to simple local file systems, so things like the MS-DOS/FAT file system where a single local device, or partition, yields a single volume. Given that reality, if your goal is to build a network file system today, your only option is to use a KEXT. However, any work you do in that space is likely to require significant refactoring in the future.
