[process-component-mismatches-diff]

The following universe packages have new reverse dependencies
in main or got seeded. They need to get a MainInclusionReport and be
promoted, or the reverse dependencies in main need to be dropped:

 
  o python-rfc3987: python3-rfc3987
    [Reverse-Recommends: python3-jsonschema (MAIN)]
 
  o python-uritemplate: python3-uritemplate
    MIR: #1820223 (In Progress) [MIR] python-uritemplate as dependency of mailman3
    [Reverse-Recommends: python3-jsonschema (MAIN)]
  o webcolors: python3-webcolors
    [Reverse-Recommends: python3-jsonschema (MAIN)]
