summary
Claim: yes it can be improved by rethinking data as transformations and moving work to the compiler. Uses modern C++ features (C++20 Concepts, ranges, void_t, templates and requires) and proposes transformation-oriented design implemented with compile-time functional programming and type lists and transform packages. Prototype replaces virtual-based image loaders with a typelist of static transform packages, removing virtual calls and enabling compile-time dispatch; example code is rough but the approach demonstrates better modularity and optimization opportunities.
