We changed the default in debian to re-autoconf on build a few years
ago precisely so that changes in the tools (particularly new arch
support) were picked up even by code that was not being re-released or
released without autofoo updates.  This has worked remarkably well.

So changes in the tools will get used, at least in that context, which
includes a fairly hefty pile of crufty old code. I have no feeling for
how many packages are actually affected by this. Is there a quick way to test?
