[BangPypers] Do you pin your requirements.txt ?

I am quite positive that people who are in favour of pinning have 
experience
in equally long term maintenance of code.

That is very simplistic view. We unfortunately can't deploy multiple 
times in a day.
And we have limited resources that any update of a dependent package is 
taken
as a separate exercise.  For us we are also dependent on communication 
with the
client which completely rules out unplanned releases.
