I guess, the limits field is not a bad idea, I actually recommended feature flags mostly because there was no clean place to put it and a category for just this limit is weird, are there any other limits that there is a chance for it to come up ?

Ideal candidates for platformFeatureFlags are boolean properties indicating whether a given feature applies to the active platform. In this case, it'd be appropriate to introduce the collectionImportSizeLimit property at the top-level platform definition or say, within a new field like limits.

@AndrewBastin, appreciate your thoughts on the convention here.

EDIT: Discussed separately, we'll be including the collectionImportSizeLimit property within a new limits field. This field can be extended to impose limits for file uploads with multipart/form-data content type when workspace syncing is enabled down the line.

@jamesgeorge007 I have implemented the new limits field.
