Changes between Initial Version and Version 1 of Ticket #47987, comment 41

initial	v1
1	1	Reopening to reevaluate the need for the `create-image-subsizes` action in `post_process_item()`.
2	2
3		This came up during implementing use of the end-point in https://github.com/WordPress/gutenberg/pull/17858. ~~The purpose of the new end-point is~~ allow post-processing of an uploaded file to continue after a fatal error. At this point the server "knows" what needs to be done, there is no point in limiting the action.
	3	This came up during implementing use of the end-point in https://github.com/WordPress/gutenberg/pull/17858. removing `create-image-subsizes` would work well when the new end-point is used to allow post-processing of an uploaded file to continue after a fatal error. At this point the server "knows" what needs to be done, there is no point in limiting the action.

5	5	The code there can be changed to test if the attachment is an image and if any sub-sizes are missing, then create the sub-sizes if necessary. In the future if post-processing is implemented for other file types, that can be added as well.
