Hello! Do you mean this change? https://codereview.qt-project.org/c/qt/qtbase/+/559265
If so, my bad! My motivation is described in the commit, but basically QtProtobuf is quite heavy on QMetaProperty usage, and trying to resolve the 'menum' was quite a bottleneck for properties that were not known as enums in the metatype system (and thus treated differently). When you say you are doing 'this' dynamically, do you mean building a meta-object? Or enum?
