I'd like to humbly ask that CONFIG_USB_SERIAL_CONSOLE=y be added to the kernel config so that those who have hardware that lacks a real serial port can attach a USB serial device and see startup messages. Debian denied this request a few years back as "too unusual" of a use case, but I feel that this could be very useful to the Proxmox community. Thank you.
FEATURE REQUEST: Please consider adding CONFIG_USB_SERIAL_CONSOLE as a built in to the kernel

Yes, I use serial too, but with "real" ports. On servers this is not possible, I use netconsole for the sake of reading the startup messages. Maybe this could solve your problem too?
Unfortunately
netconsole appears to suffer the same issue as USB SERIAL CONSOLE. It's built as a module in the kernel CONFIG_NETCONSOLE=mso you would not see anything until after the kernel modules are loaded, missing GRUB and any issues early in the boot process.
grub obviously not, but the whole kernel ringbuffer is sent via netconsole after it has been loaded from the initramfs. I'm using this for decades and it is e.g. directly supported and implemented in RHEL for really decades.
