It is possible to write to /usr/local and /usr/local/texbin was one of the choices discussed. The /Library/TeX/texbin location was chosen since that is completely under the control of MacTeX (which actually installs that directory and contents which are used by the TeX Distribution Preference Pane and the most recent version of TeX Live Utility to change active distribution). PS: it's a good thing that /usr/local under El Capitan is still writable by MacTeX since that's where the TeX Live Distributions are installed.

One other thing to note: MacTeX-2015 not only installs the /Library/TeX/texbin link to the binaries (as well as /usr/texbin on pre-El Capitan OS versions) it also changes the PATH to use /Library/TeX/texbin for Command Line use. Everything just works! How Mac-like! :-)

Good Luck,
