I measured the memory footprint when I combine my two changes:

* disable Py_TRACE_REFS: https://bugs.python.org/issue36465
* disable/remove serialno field: https://bugs.python.org/issue36611

python3 -m test test_asyncio, without => with the change: 34,038.0 kB
=> 30,612.2 kB (-3,425.8 kiB, -10%)

A reduction of 3.4 MiB on 34.0 MiB is quite significant, no?
