Mono, as i understand it, implies it's a single channel with the entire audio signal, opposed to simply "1 channel" which can be anything, even LFE. Apple has separate values for FC and mono, and Quicktime files with one stream per audio channel will signal the channel meant for the center speaker as FC and not mono (something that affected lavf parsing of such files, and forced us to do some heuristics).
In practice yes, you can simplify it as mapping to FC, and in the absence of said speaker, just play it on FL. But there are scenarios where the distinction is needed, and we currently lack a way to properly signal this.
