Thanks. We discussed this in triage: This could be done (via two passes over the package), but might not be worth the complexity. Seems like a low priority.

Change https://go.dev/cl/541155 mentions this issue: go/analysis/passes/testinggoroutine: report by enclosing regions

gopherbot pushed a commit to golang/tools that referenced this issue Nov 21, 2023
This adds support for t.Run() statements. The new version
performs two passes. The first pass collects all of the
`go callee` and `t.Run(name, callee)` statements. The second pass
inspects each callee FuncDecl or FuncLit for a call to a
tb.Forbidden() function.

When the enclosing callee function called from an t.Run() statement,
it reports when tb is declared outside of the body of the
enclosing function.

Fixes golang/go#63799
Updates golang/go#63849
Updates golang/go#48124
