Good afternoon Rich.

1.  Correct.  MIL-I-46058 is inactive for new designs, but not cancelled.
DSCC maintains the QPL.  Any vendor can qualify a new coating if it falls
into one of the five existing chemical families.
2.  For CC-830, yes, you would have to get the test report and verify
yourself that the test data meets the CC-830 requirements and that ALL of
the CC-830 tests have been passed.   There was discussion a few years back
of IPC being a certifying authority for in essence, a commercial QPL, but
the idea met with much resistance, but not perhaps to the level of rioting
villagers you describe.
