If people use includeDependenciesRecursively: false with forgetting to set InputOptions.preserveEntrySignatures: false | 'allow-extension', it's better to raise errors for invalid cases.
Otherwise, people will think it's expected to create non-entry exports from entry chunks, which is against the intention of InputOptions.preserveEntrySignatures: 'strict'
