I share your opinion here, I'd rather see the COMMANDS thing as an application bug as a user who doesn't read the configuration but just uses it could also get owned with a valid command. The only difference I see is that as far as I understood the command is only executed after user action while the configuration value is read without. The manpage utf-8 conversion is the real vulnerability as it is possible to exploit a victim by opening a crafted manpage in gmanedit.
