You could get away with using the Media & Text, Columns, or even a Heading and Image block to create something like the How-To block in this plugin. A theme author could create a pattern with the existing core blocks and do something similar. Basically, there are many paths that can get you to the same place or at least close enough to it. The big difference from a user point of view is going to be the design and options to customize the "dot type" the plugin offers.

Agreed on the half a dozen tabs note. I have so many plugins in my test installs that all these various blocks are overlapping. The early prototypes of the blocks management screen look promising. A single block collection plugin may do it better. We'll see where things go.
