I find it hard to believe they only recently added GPT partitioning support , or was there some other issue happening with the removable storage mediums above a certain amount?

Nah, it’s just SDUC cards are a different hardware design.

  I’m not sure I’m following, what was the technological leap here? I know that the SD, SDHC, SDXC, etc. are marketing terms and their limitations are based on other factors, much of the previous ones are file system related.
  
  SD - FAT16 Volume size limit, Practical limit 2GB, Max limit 4GB
  
  SDHC - FAT32 limit Set at 32GB by Microsoft (fake limit)
  
  SDXC - 2TB limit, Maximum partition size for MBR partition Scheme.
  
  I assume that it’s a similar story here but it might not be, if so I’m curious as to what changed.

    The I/O commands are different as well, the hardware has to support SDUC.
