To get old tab bars on Safari for macOS 12, create

/Library/Preferences/FeatureFlags/Domain/Safari.plist

copy the above into it, and reboot.

---

The feature is controlled by

+[FeatureAvailability isUnifiedBarEnabled]

which calls os_feature_enabled, which searches in /System/Library/FeatureFlags/Domain/Safari.plist and /Library/Preferences/FeatureFlags/Domain/Safari.plist.

I copied the System file, removed the other flags, and changed UnifiedBar to false.

The old layout is now the default in the latest Tech Preview and Monterey Beta. It can be changed to the single-row layout in the preferences.

This is random, but do you know if it is possible to move the Bookmarks Bar to above the Tab Bar?
