What is known so far comes from the other direction:
These projects were analysed and named FCOS among their alternatives. The relationship is not symmetric — how FCOS rates them is a separate judgement, made when FCOS is analysed in its own right.
calls FCOS “choose it for a fully convolutional one-stage anchor-free detector baseline if you do not need transformers and can use unmaintained code.”
