Most attempts at developing new LLVM downstream architectures simply fail at keeping up with upstream LLVM, especially across major releases. Perhaps these projects should focus a bit more on getting at least some of their simpler self-contained changes to be adopted upstream, such as custom optimization passes. Once that is done successfully, it might be easier to make an argument for also including support for a newly added ISA, especially a well-known ISA that can act as convenient reference code for the project as a whole.
