As per link below: this file has GPL-2 code and cannot be migrated under a github rooted at ASWF (where everything has to be compatible with Apache-2).
openfx/Support/Plugins/Generator/randomGenerator.cpp
I don't know if there is a volunteer to do a Pull Request, seems it could be just changed to srand and rand
reference analysis:
For people who don't know Apache-2 (or MIT or BSD-3) code can be used in a GPL-3 project but not the reverse.
