Did we have an expected new behavior for this? I know we've floated the idea of taking the diff of the apis before / after adding an extension and temporarily highlighting categories / blocks that have been added by the extension, but I've only heard of it as an idea / not gone through a complete design? For what it's worth, the description does say where the blocks are added:

I think it would be a good feature to add, just not sure how much work it would be yet / likely would come in a bit hot. Removing next release for now.
