"central_bundles-xxx" in Nexus UI's staging repository

Question

I just deployed my first project to Maven Central and found three repositories together with the one I staged. Two of them are closed and one of them open. They all point to some

https://oss.sonatype.org/content/repositories/central_bundles-1133/

Can I drop these repositories or what is their purpose?

Answer 1

Well, today I received an email that repositories are shared among users and those entries represent other's data and should therefore NOT be deleted.
