Just my 2 cents, but since the specification specifically allows theme
authors to do whatever, if ECM doesn't support that then ECM appears
not spec compliant.

The only way to install an application specific Breeze icon is to hard code its location, for example "${KDE_INSTALL_ICONDIR}/breeze/actions/22/". I raised a bug against ECM about this, but not unexpectedly it has been rejected as a Breeze issue (see https://bugs.kde.org/show_bug.cgi?id=476208).
