As discussed during CFT meeting (22.01.2026) there were some obsolete reqs defined:

• The component shall accept keys that consist solely of alphanumeric characters, underscores, or dashes.
  • To be rechecked.
• The component shall encode each key as valid UTF-8.
  • Should be replaced with valid and printable ASCII?
• The component shall limit the maximum length of a key to 32 bytes.
• The component shall serialize and deserialize all values to and from JSON.
  • Might be valid, but it shouldn't specify JSON
• The component shall limit the maximum length of a value to 1024 bytes.
