This is part of the cancer, though. People notice that even though their TTL is low, changes don't propagate, so they set it even lower in an attempt to compensate.

It goes both ways, a vicious circle.
TTLs aren't respected -> people try lowering them even more.
Lots of low TTLs -> people configure a minimum or ignore them.
As an infrastructure provider with limited connectivity, seeing lots of low DNS TTLs means I'll just configure a saner minimum (say 1h) and consider it not my problem.
