Reverse dependencies of upgraded package

[wes-a2ai]

If a package is being upgraded (either by future --upgrade flag or by specifying a new repository), the user should be have the option to be notified that it may affect other packages

i.e. ggplot2 depends on withr >= 2.5.0. If I have withr 2.5.0 installed, but want to upgrade to 3.0.0 for withr functionality, I sometimes will want to know that ggplot2's behavior may be changed

IMO this can be solved through a series of separate commands/flags. For example uv tree to show the dependency relationships. There is likely some combination of specific incantations to design around like plan --upgrade, plan --upgrade --with-dependency-impact or something like that which presents the data in different ways.
