Most disheartening is the way Zeev Suraski pleaded for votes against the size_t/int64 patch in a mail[1] titled "A call for help (urgent)" because, I quote, it "negates months of hard work". That was only a few days after Zend's secret project had been uncovered.
The size_t/int64 refactor has been going through several iterations and RFCs since 2013.
