What you seem to be missing is that if updating a Makefile.am or
configure.ac (eg. with bzr update) to remove the generated file. Then a
following "make clean" or even distclean will not remove the old files
from the build area. This will keep them hidden and possible affecting
the build for people who may not be aware of the change.

It can also hide makefile mistakes between $srcdir and $builddir or the
matching top_* variables if the developer changing the makefile is
working in-tree.

PS. I found Henriks advice years ago never to use in-tree builds to be a
good rule to work by and never looked back. These files are not a
problem when working out-or-tree, all we see in "bzr status" is the top
build directory.
