Based on review feedback on https://github.com/carbon-language/carbon-lang/pull/6215#discussion_r2430177644 There are some intermediate commits with alternatives, finding other ways (non-templates) to address the layering boundaries between `ValueStore` construction and `CheckIRId` tagging. But, yeah, template seems like the way to go - certainly in terms of terseness and probably in terms of extensibility to other Id tagging as/when needed.
