Hmmm id prefer to make tests smaller or increase parallelism to increasing test time, or else dev iteration time slows down due to slower tests.

Yea, but its less likely circom compilation and tests will run in default timeout. We already have smaller circuits for testing individual templates. This was necessary in my machine to finish the tests.
