From comments on #725, about avoiding duplication when data is duplicated between entries that differ only in name:

@ddbeck:

It might be nice to some day have this package to allow a sort of "see also" format (something like { "__compat": { "see": "css.properties.some_prop" } }) to avoid the duplication, though hashing out what that's supposed to mean exactly might be complicated. Should I open an issue for that or is it too rare to matter?

@Elchi3:

I think the "see also" format is interesting. For APIs, there are sometimes entire feature trees that have the same compat data and we're repeating this info leading to some giant JSON files. On the other hand, and from a data consumer point of view, I feel like I don't want to deal with yet another thing to resolve for displaying the data :-) File an issue, good to have a discussion about this on record.
