Same with OpenRISC, at the time the RISC-V project was started.
ARM too. The RISC-V design was fairly well advanced by the May 2011 spec, and IMAFD (and E) were in essentially their current form in the May 2014 spec.
Aarch64 was announced between those two in October 2011, with the first 64 bit Apple iPhone 5s shipping in September 2013 and with ARM's own cores such as Samsung Galaxy S6 in April 2015.
The first commercial RISC-V chip (SiFive FE310) shipped in December 2016.
