- Alternate fix to #67844 that calls `_export_file` for all resource types instead of implementing `skip()` for customize functions.
- Fixes#93823.
- Moved logic surrounding "Skip" and "Keep" imported files to happen before resource customization. Fixes#93825.
- Also fixes an issue that I suspect might exist where progress bars during export were incorrect due to imported files in the project that are configured as "Keep" or "Skip".
