I ran this on our benchmarking infrastructure, and it seems to speed up the telco benchmark (which is the only decimal benchmark in the suite) by about 2%: https://github.com/faster-cpython/benchmarking-public/blob/main/results/bm-20240429-3.13.0a6%2B-59ac30f/bm-20240429-linux-x86_64-nineteendo-use_PyTuple_Pack-3.13.0a6%2B-59ac30f-vs-base.png

If it affects the telco benchmark, and this is not a random fluctuation, there should be possible to create a microbenchmark that shows the tens percents difference.
