// On Android Virtual Devices we heavily depend on logging, even in
// production builds. We do this because AVDs are components of larger
// systems, and may be configured in ways that are difficult to
// reproduce locally. For example some system run tests against
// third-party code that we cannot access. Aborting (cf. assert) on
// unimplemented functionality creates two problems. First, it produces
// a service failure where none is needed. Second, it puts the
// customer on the critical path for notifying us of a problem.
// The alternative, skipping unimplemented functionality silently, is
// arguably worse: neither the service provider nor the customer will
// learn that unimplemented functionality may have compromised the test
// results.
// Logging invocations of unimplemented functionality is useful to both
// service provider and the customer. The service provider can learn
// that the functionality is needed. The customer learns that the test
// results may be compromised.
