Oh sure, it's fixable and something you can work around, but having your build system responsible for "machine is unresponsive and acts like it's out of disk but you've got >100GB space remaining" is a real pain in the ass. Running out of inodes (and specifically, that you can run out of them well before running out of disk space otherwise) is also really not an obvious failure mode to most people.
