> The current schema version is 12 but the implementations for Go, Rust, C++ and Java are all listed as draft 7

It's actually 2020-12, which is two versions after Draft 7 (they shifted from Draft n to YYYY-MM after Draft 7, and since then have had 2019-09 and 2020-12.)

And that's true of most languages, though there is some 2019-09 support. (It really doesn't help that there is also OpenAPI which baked in a variant—“extended subset”—of Draft 5 JSON Schema.)

OpenAPI 3.1 which was released recently, uses JSONSchema 2020-12 as the primary schema format. As a result, we can expect further consolidation of tooling, etc in the community.
