Clang code model index out of the build folder

Why is the Clang code model index placed into the build folder under the .qtc_clangd/?

Because of this, we can not delete whole build folders anymore because it also deletes the index.

I would appreciate placing this index in the QStandardPaths::AppLocalDataLocation or maybe to the custom location that will be configurable in the global settings eg. E:\qtc_indexes.

What do you think about this? It's real? Or you will not make a change like this in any way?
