This doesn't solve the issue with "too many tests", but one of my teams addressed this to some extent by writing "blueprints" for test scaffolding that specifically aims to surface the scenario under test.

Was initially hand written as part of our codebase before AI, just extracted it as MIT, OSS since there's no secret sauce here. But really cuts down on test verbosity and makes it much, much easier to read, review, and evaluate tests.
