Currently some Jenkins jobs default parameters including the "SPLENV_REF" (rubin-env version) in the job Groovy file instead of or in addition to the pipeline Groovy file. Since changes to the former (or things read in by the former like the config YAML) are only picked up when the seed jobs are rebuilt while those to the latter are picked up every time due to fresh git checkout, it would be better for all defaulting to occur in the pipeline files. Please make this happen.
