For example, snapping or pivot point.
The slowdown happens in complex files with drivers which use scene
properties as input. Can be seen in the demo file from #117335.
This change adds ability to mark RNA property as required to bring
the evaluated ID up-to-date, but not do possibly expensive tag for
drivers.
The tool settings possibly can be tagged as do-not-do-deg-tag at
all, but safer seems to follow the current behavior a bit closer.
