Review Comment:
the doc and name should be adjusted to the list -> collection change in the
return type
> Expose checksum service on API
> ------------------------------
>
> Key: MNG-7957
> URL: https://issues.apache.org/jira/browse/MNG-7957
> Project: Maven
> Issue Type: Dependency upgrade
> Reporter: Tamas Cservenak
> Priority: Major
> Fix For: 4.0.x-candidate
>
>
> Resolver since 1.8 has extensible checksum SPI:
> [https://maven.apache.org/resolver/about-checksums.html]
> I think it would be worth to expose that not directly, but via some sort of
> Service in new Maven 4 API?
