I think this is a fine description, and respect your reasoning! I think there is in this case, no conflict: Keep the OS-managed packages strict about dependency security, and let the user run the .deb or compiled program Fresh (or whatever software) has provided. So, I think your (Debian perspective), and Fresh (Providing binaries for download, including as a multi-linux script) is on the simpler/easier/just-works end of installing software. No conflicts. Single-CLI line install either way.
