Look at the size difference of configure.ac and configure. For example
So one each configure.ac line you have 53 configure lines. You're used
to review that these 53 lines really reflect the cahncges in the
master? W/o running autotools youirself to verify this?
If you do so w/o autotools' aid, then you're a masochist. ;)
If you use autotools, then why not use them in the sepcfile and have a
manual step to perform? Manual steps either slow down the process or
are easily skipped and not done at all ...

Please read the docs. Autotools and even the author of the
AM_MAINTAINER_MODE recommend to *not* turn off maintainer rules for
very good reasons. These reasons apply here as well. This has nothing
to do with released packages or released software whatsoever.

If you need a recipe, then automate it.

Help, we're talking in circles, let's agree to disagree! :)

It depends on the viewer I guess.

Sure, but a lot of truth as well. The general rule is that when there
are build chains, only touch the highest master, not intermediate
A more comparable analogon: You wouldn't patch a LaTeX generated
(uncompressed) pdf file if you would just like to fix a typo.
Anyway let's agree on disagreeing, I really just wanted to add my 2¢
and now the meter is already at 2€. ;)
