I'd like to request adding information about package license changes to verbose build output, e.g. adding something like '{{ Sleepycat => AGPL-3 }}' for the sys-libs/db upgrade. Rationale: license changes sometimes surprise software developers, and if they involve changing to a more restrictive license, they can effectively cause user's local programs to violate the license terms. For example, if you made a GPL program using sys-libs/db, you can't upgrade to AGPL-3 db without relicensing your program first. A verbose information in emerge output (or even possibly a warning below depgraph) would certainly be better than letting it silently happen.
