Yes, that should be better than building with just PACKRATDATA. However, why not omit both macros? That's simpler and has fewer issues with compatibility and data quality.

Then all those inconsistencies will be resolved, but Asia/Hanoi will be gone.

It's not gone compared to tzdb proper, which has never had an Asia/Hanoi entry. PACKRATDATA=backzone PACKRATLIST=zone.tab is designed to resurrect out-of-scope and lower-quality pre-1970 data that was formerly in tzdb proper, not to drag in all out-of-scope lower-quality pre-1970 data that exist in backzone.
