Especially the former can be troublesome if they don't cause a build
to fail. For example, it can lead to issues such as undefined/unsubstituted
macros, dropped lines from Makefile*.in templates, files like config.h.in
or even m4 files.

Packaging guidelines that ask packagers to run autoreconf always will
lead to packagers adding something to a spec file without spending
extra time on carefully examining the results.
