Unfortunately, there's plenty of vendors that suck at writing firmware, and most usually give up on updating it immediately after they've EOL'd the hardware revision. The hackintosh project mostly works by replacing the bugs from the vendor firmware into the bugs that apple expected from their x86 line of pcs.
If most vendors suck at writing firmware, it might be a problem with the spec though.
BIOS didn't have a spec at all, it was hacks stapled to reverse-engineered chips that were Good Enough To Ship for IBM decades ago.
Most of the alternatives require brand+model specific kernels and boot mechanisms, at least UEFI has a standard. I dream of the day smartphones run UEFI instead of the weird factory bootloader + custom uBoot mess that we're in right now.
