IMO the _Bool is better because that lets the compiler do its magic.

Of course! :) No critisism intended.

Just the notion: "your" guys was the ones to make those to boolean(_t),
and now you seem to want to patch them away because I tried to make them
more general.

B_FALSE -> false
B_TRUE -> true

How are you sure "needflush" is, for example, not a counter?
