Why not BDWGC?

[LuciferLeo]

I've heard that the reason why python uses reference counting rather
than tracing collector is because python cannot determine the root set
for its various C extensions.
But provided that BDWGC(full name: Boehm-Demers-Weiser conservative
garbage collector) is conservative --- can be used for C, and
opensourced, why python not adopt it as its gcmodule?
