Can HEIF media be streamed?
HEIF (https://en.m.wikipedia.org/wiki/High_Efficiency_Image_File_Format) seems like a great container to replace many image formats. It can use HEVC for video. But, like video formats, can it be streamed or progressively downloaded? For instance, could a cover image or thumbnail be downloaded first and displayed to the user, while waiting for additional larger resolution images, all via one file?

From what I've seen from WWDC session about HEIF & HEVC, it is possible to stream HEVC video via HLS. HEVC can be accessed/consumed using the following methods:
Excerpt from WWDC: (Introducing HEIF and HEVC)
Accessing HEVC
HEVC movie support
AVFoundation--supported media source
PhotoKit--movies, resources and edit
WebKit--hardware support and macOS desktops
HTTP Live Streaming (HLS)
Apple apps
But I am not really sure about the progressive download.
