"Delete previously generated files when not regenerating" not working for some libraries

Comparing CMake projects with STM32CubeIDE projects shows many unused libraries added as source for CMake project:

  • \Drivers\CMSIS\DSP (44.7MiB)
  • \Drivers\CMSIS\Core (1.8MiB)
  • \Drivers\CMSIS\NN (1.5MiB)
  • \Drivers\CMSIS\RTOS2 (112.KiB)
  • \Drivers\CMSIS\RTOS (40.0KiB)

Total size of these extra unused files is 48.1MiB. I think this is because initially I selected "Copy all used libraries into the project folder" (I think this is the default option). But when I check "Copy only necessary library files" they won't be removed when regenerating. Despite "Delete previously generated files when not regenerating" being checked.
If I delete them and generate again then they won't be added again and build works fine. So they clearly are not needed.
I'm using the latest version: STM32CubeMX V6.15.0

Maybe they don't count as generated files?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

The unused files in the drivers Drivers are not "generated" either, but also copied unmodified. But these files are removed when I check "Copy only necessary library files". So this is an inconsistency.
Perhaps those files are not counted as libraries, but MCU specific files and the DSP files are counted as libraries. It perhaps only copies them, but doesn't uncopy them.
Maybe that would require a checkbox "Delete previously copied library files when no longer used".
Either way from a user perspective I think a bare blinky project doesn't need nearly 50MiB of source files. It clutters my git repo.
