We are in a situation where previously "supported" platforms (by Oracle) 
are no longer supported as, AFAIK, no one has stepped up to take 
ownership of said platforms - which is a requirement for getting a new 
port accepted into mainline. Without such ownership the code may not 
only bit-rot, it may in time be stripped out completely. Any interested 
parties would then need to look at (re)forming a port project for that 
platform to keep it going in OpenJDK (or of course they are free to take 
it elsewhere).
