How can we make that better? Exactly.

The simple way now AFAIK is to exclude it, then bitbake prints backtrace e.g. dnf ├── libdnf │ ├── libsolv │ └── json-c └── sqlite3 dnf -> libdnf -> libsolv libsolv is needed for dnf. so would be good to have a query command or simple tool to show that? something like apt-rdepends output.
