Comment (by aaronrobertshaw):

 Great discussion and ideas here!

 I like the suggestion of a single registration function for style
 variations. There could be a future where theme and block style variations
 are more interchangeable. Long term, a single registration function should
 prove easier to maintain, evolve, and discover.

 To accommodate registering theme style variations, we'd need a registry to
 store them like the block styles are in `WP_Block_Styles_Registry`.
 Unfortunately, `WP_Block_Styles_Registry` was marked as final when it was
 created which makes it difficult to experiment in Gutenberg first.

 With either `register_block_style` or `WP_Block_Styles_Registry`, if their
 scope is expanded beyond block style variations, they probably need a
 rename too.

 One approach that might make exploring this feature easier, could be,
 creating a more generic registry (e.g. `WP_Style_Variation_Registry`) and
 a new global function (e.g. `register_style_variation`). The existing
 function and registry class could then be updated to essentially be
 wrappers and perhaps even deprecated eventually.
