I noticed. But language families tend to have their own small-scale 
tendencies - I thought this thread was after more universal tendencies

No, I didn't mean "total loss of contrast" either. I guess the terminology 
is a bit ambiguous here.

Anyway, the question remains: are there really numerous languages that have 
shifted /b/ to, say, /B/ universally? I'm sure you have one or two examples, 
but these could be just random exceptions. Meanwhile /p/ > something else 
universally has happened in more than just one language family. (Not always 
thru fricativization, however.)
