Thought I'll post an update here. Almost a year later, the File Provider API version (https://support.google.com/drive/answer/12178485?hl=en) rolled out to my machine. And I can confirm that standard Spotlight (and thus Alfred) search works again.
I believe Vitor's plugin is still a viable and more feature-packed alternative, but now a built-in alternative exists. At least for those who got the update from Google.
@mishamsk Do you find that this works fully? It is working for me but only partly. It doesn't seem to find some files and folders. I can't tell if there's any pattern to those it can find.
