Is the Boot Process of the Raspberry Pi 5 Still Linked to the VideoCore Binary Blob?

Question

Previous models of the Raspberry Pi relied on a proprietary binary blob that acts as a black box, is this still the case?

In a way, yes, there is still a bootloader that handles network booting, install, NVMe, USB boot. It is proprietary but it is not encrypted or open source. 
 It's main task is to monitor clocks, power and encryption key handling for encrypted boot. Though it is now handled inside of an EEPROM so there is no start.elf or bootcode.bin required.
