And honestly, it's a good fear to have; there are contexts where it still just doesn't work.

Last I checked, the standard answer for GNU make is "Spaces are expected to break the tool, that's working as intended, it will never be fixed." And because we build our towering edifices of software on the pillars of the past, I can't guarantee to you that a project of arbitrary complexity won't try to cram a list of filenames through a make script.
