Question about lightweight DITA maps

Hi all,
Passing along a question that came up recently - is there support for a markdown version of the lightweight DITA map? If so - is there a convention on how to refer to it? For example, would you call it a "mditamap"? I'm thinking of a case where you need to  refer to that map from a full DITA map, and might want to set something like format="mditamap" on the reference.
It looks like there was some discussion of this back in 2019, but I'm not sure how it resolved -

Thanks,
