Hey, Blueprint rendering was already thread-safe. Only the function/filter registrations, IF done during rendering phase, was not thread-safe. I have just pushed small update to make even these thread-safe now. Entire library is now fully thread-safe. Updated README as well. Thanks for pointing this out.
