Functionality of queryAttachmentInfos in the 4.0 JSAPI?

[SethGreylyn]

In the 3.X JSAPI, the FeatureLayer class has a queryAttachmentInfos method, here: https://developers.arcgis.com/javascript/3/jsapi/featurelayer-amd.html#queryattachmentinfos

This method does not seem to exist in the newest (i.e., 4.X) version of the JSAPI. Is there any way currently to recapitulate the 3.X functionality using the 4.X API, or will that functionality only be possible when 4.X is brought closer to parity with 3.X?

Seth,

Look here:

Choose between version 3.17 and 4.0 | ArcGIS API for JavaScript 4.0

Or here:

Functionality matrix | ArcGIS API for JavaScript 4.0

This will show you the differences between the api.

Thanks, Rickey! I'll keep that matrix in mind the next time I notice a discrepancy.
