If there's appetite to go even lower than 50, the relevant counts are:
8898 21
6 22
19 23
87 24
13 25
1 27
1 29
14 30
4 31
39 32
1112 33
33 35
1 39
43384 40
35 42
12281 50
Since the zone count for 20 in mid October was 531,146, that seems to be
the lowest realistic limit we can impose, if we're willing to apply enough
pressure to also get the ~66k zones between 21 and 50 to make changes.
