That is a problem with coding practices, not with the method used.
All you need to do is write a redirect() function used in all pages and
call it instead of header(). Then you have one point to change if you
need to make a change as you describe. The fact that someone did not
do this does not mean the underlying method is a poor idea. It just
means they didn't anticipate the need for application-specific code as
part of the redirect operation.
Put another way, it's a common error to fail to build an abstraction
layer for this type of low-level operation, but it doesn't mean using
the low-level operation is a mistake. The error, if there is one (and
I'd say there is in the scenario you describe) is in not noticing the
need for an abstraction layer.
