I propose that we make Akira Hatanaka the code owner for the Mips code generator.
He has worked on the Mips code generator for four years now and done high quality work that whole time.
He is the key person inside of Mips for reviewing patches and giving advice to other developers regarding new Mips work.
To assure the future quality of the Mips port, I think it makes sense to formalize what is already true inside of Mips, to the larger community that may contribute to Mips.
We have licensees with their own variations and extensions and there will be other people wanting to make changes to the Mips code generator outside of Mips.
Richard Sandiford has held this position for the gcc Mips port for many years and it has helped greatly to make that code generator solid.
