Now aside from Verizon versions of Samsung devices, are most if not all other carriers models have an unlocked bootloader or the ability to be unlocked? Now that I think about it, it's a shame there isn't a running list of model/carrier/android version/root/bootloader status.
There doesn't have to be a running list. You could research all this, all the information is out there. If anyone States "the S5 has an unlocked bootloader" you can take it to mean they're discussing the international version. There are many additional carrier versions that that wouldn't describe.
Verizon has always had locked bootloaders, AT&T have recently started locking their phones, t-mobile and sprint generally have unlocked bootloaders.
As far as brands go, htc and Motorola generally have highly encrypted bootloaders, while samsungs don't, but recently Samsung has been tying their bootloader into the kernel which makes downgrading impossible. Samsung has traditionally always been developer friendly, even on Verizon, until the s3 came out. All of this doesn't matter if you're on Verizon, every single phone is going to have an encrypted bootloader lock.
