I'm talking about the WinRE partition, which is required to boot Bitlocker encrypted boot partition (and Bitlocker is enabled by default). Enabling Bitlocker without one results in an error message, and Windows happily recreates/resizes the WinRE partition on every (OS) upgrade by simply reducing the size of the main partition. It has been a long time that the size of the ESP is not enough for all the stuff that Windows wants to do on preboot. For the record, and showing again the unfairness of the entire MS monopoly situation, most commercial UEFI implementations out there happen to understand NTFS. This allows e.g. a Windows pendrive to boot no matter how the user formats it.
