Can anyone help me understand why they changed the model naming convention?

BEFORE: claude-3-7-sonnet

AFTER: claude-sonnet-4

Seems to be a nod to each size being treated as their own product.

Claude 3 arrived as a family (Haiku, Sonnet, Opus), but no release since has included all three sizes.

A release of "claude-3-7-sonnet" alone seems incomplete without Haiku/Opus, when perhaps Sonnet is has its own development roadmap (claude-sonnet-*).
