What do we think about always autoreconfing? (was: Re: Fedora 35 Change: Autoconf-2.71 (Self-Contained Change proposal))

What is the current thinking in Fedora about always running
"autoreconf -i" during builds that use autotools?

In Debian it's been recommended for a long time:
https://wiki.debian.org/Autoreconf

I maintain a few packages where I attempt to toggle autoreconfing
based on whether patches touch build files.  If a downstream patch is
applied which touches any of configure.ac, Makefile.am, or several
other files, then the build will attempt to run autoconf/automake and
usually fail.  These packages have:

  # If there are patches which touch autotools files, set this to 1.
  %global patches_touch_autotools %{nil}

  %if 0%{patches_touch_autotools}
  BuildRequires:  autoconf, automake, libtool
  %endif

  %prep
  ...
  %if 0%{patches_touch_autotools}
  autoreconf -i
  %endif

This is a kind of optimal solution, but also hard to get right - I
often find myself forgetting to set the %global correctly after
applying or removing downstream patches.

The cons of always autoreconfing are that it slows down builds,
sometimes considerably.  It also could fail - I noticed that autoconf
2.71 has several incompatibilities with the most widely used autoconf
(2.69).
