Yes, of course. The idea is good!

No, I don't have any.

It's just that some of our (completely unrelated) source
generation tools (written in Perl) internally use some to write
content. First we had some prepend/append hooks but later found
it stronger to overwrite the content writing functions.
For example, when having some

   @lines = (header(), content(), footer());

sometimes maybe content() could be overwritten to some

   # comment out a block
   sub overloadedContent() {
     @content = content(); # or self->SUPER::content()
     map { $_ = "# $_" } @content; # or whatever
     return @content;

or replace some identifiers inside, remove something or alike.
Probably all this are examples of DONT-DOs because relying on
internals that change without prior notice.

But I think this is out of scope here. Much too complicated and
it would be more customizing automake than using a feature of it.
