Is there anything to be gained in having Linux run in UEFI mode?

From what I've found the technology ultimately gives little security to the OS, it is used by some manufacturers to lock out the option of installing another OS, and M$ use it to stop pirated versions of their products being used, it can in some cases help stop rootkits, but it has been overcome by phreakers already, personally I don't have a use for it
