- Deserialization of binary module dependencies was still relying on stale code (e.g. 'currentModuleImports', 'currentOptionalModuleImports') from serialized import strings, instead of the now in-use import infos. - Imports without a source location (e.g. implicit imports of stdlib) were not getting serialized at all - Optional import arrays were not being written out at all
