Currently there are a lot of packages in gentoo's tree that are installed without warning they are BINARY. For example, app-office/upwork, many more dev-java/* with precompiled .jar files. It's not a proper behaviour for source-base Linux distribution. There was practices to create `*-bin` packages (`maven-bin`, `icedtea-bin`) or add `-binary` USE-flag (`scala`, `seabios`, `vgabios`). But many packages that are purely binary do follow neither. Reproducible: Always Expected Results: Binary ebuilds, packages with precompiles binaries must be keyword-masked (for example, with `BINARY!!!!!!!!` keyword) or featured (`allow-binaries`) or must have USE-flag with clear semantics ('binary').
This is not a topic appropriate for a bug report. I suggest you discuss it on the gentoo-dev mailing list.
