Why does the JESD204C Intel® FPGA IP in base only mode generated in the Intel® Quartus® Prime Pro Edition version 19.4 require regeneration in Intel® Quartus® Prime Pro Edition version 20.1 and above?

The JESD204C Intel® FPGA IP in Intel® Quartus® Prime Pro version 19.4 shares the synchronizer from the Transceiver (PHY).

The JESD204C Intel® FPGA IP in base only mode does not contain the Transceiver (PHY), which results in IP generation failure due to missing files for this mode.
