I don't see the dependency.

$ reverse-depends -r buster src:r-bioc-biocinstaller
No reverse dependencies found

$ reverse-depends -b -r buster src:r-bioc-biocinstaller
No reverse dependencies found

I don't believe that is going to work.  See section RenamingPackages

Method, not the Clean Slate Method, if you want r-bioc-biocinstaller
to be replaced by r-cran-biocmanager during an upgrade.
