Refactor functions that handle 'packages' in consensus/votes
This is a side issue of #18840 (moved).
The code managing packages for consensuses and votes seems to be of particularly low quality.
See compute_consensus_package_lines() doing ad-hoc parsing. And see validate_recommended_package_line() doing more ad-hoc parsing and having wrong return value patterns. Fortunately, both of them are weakly tested in the unittests.
Maybe we should refactor and add more testing for these funcs?
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
