By that time it will look like something else. Maybe it will be Unix-based by then, and virtualize Windows installs for applications. Or they'll be out of business then.
Even Linux is moving on past those filesystems, except for the chunky-funky variety of embedded devices which don't use some adorable little flash filesystem you have to recook on your desktop, the ones which look more (internally) like someone shrunk the PC.
In the meantime, computing resources are cheap enough to waste them virtualizing Linux. Sometimes I boot an iso with gparted in vmware player and then connect devices to the virtual machine. It avoids so many embarrassing mistakes, it avoids reboots of the actual hardware with the stupidly-long PC POST, and you can use the same strategy on any modern operating system. That covers your ext maintenance operations. As for reading them, a very small virtual machine is sufficient to check, mount, and reshare filesystems to Windows via Samba.
Microsoft is used to controlling the dominant filesystem, they're not giving anyone a leg up.
