verb_chid(), verb_blame() and verb_identify_tpm2() all render their output via table_print_with_pager() with arg_json_format_flags, so JSON output has been implemented for them since each verb was introduced. None of them was ever added to the verb allowlist that gates --json=, so e.g. systemd-analyze chid --json=pretty failed with: Option --json= is only supported for security, inspect-elf, dlopen-metadata, ... This adds them to the allowlist and the error message. After a sweep of src/analyze/ for arg_json_format_flags, these are the only remaining verbs that render through it but were not allowlisted. has-tpm2 is deliberately not included: verb_has_tpm2() defers to verb_has_tpm2_generic(), which writes plain text via printf() and has no JSON support, so accepting --json= there would silently ignore it. The table_print_with_pager() call in analyze-has-tpm2.c belongs to verb_identify_tpm2(), which is what got allowlisted instead. The chid gap went unnoticed because its TEST-65-ANALYZE coverage is guarded behind a check for SMBIOS board_vendor and a non-container environment, so it only runs on bare-metal/VM runners.
