How can I "right size columns individually" for every Finder window, permanently?

Common question / feature request for years online and in forums. Only functional answer today seems to be the free applet "XtraFinder". But as of OSX 10.11 that tool requires disabling Apple's System Integrity Protection. Does Apple have a permanent fix available that doesn't require compromising SIP?
