Yes, unless it knows that a process providing that input is prepared to
gracefully handle the situation when writing to stdout causes an
error.  From the user's point of view,

     % mypgm | myfilter
     ... output from myfilter ...
     mypgm: error writing to stdout: broken pipe
     %

is not a friendly situation, because it makes it seem that something
went wrong.  Compare this with:

     % mypgm | myfilter
     ... output from myfilter ...
     %
