because rewriting your software is easy now, there are plenty of examples of Language Models looking at the architecture in front of them and recompiling themselves, their inference engine and harnes for faster inference on it or whatever their need may be
others have made entire OS's or gone back in time reinventing of removal of the OS and just running a single application with its own I/O stack per application
this is a guess that exotic architecture on old nodes means that the hardware can come out now at a lower price - or at least fulfill market needs at the price the market can bare without the delay - all because using exotic architecture is easy now, unstable opaque drivers are no longer an issue, and there is just a need to fulfill compute demands efficiently
