Hello,
In the near future, there is a plan to merge autoconf-2.71 to rawhide. Due to the size of the change and possible breakage of multiple packages going FTBFS. The number of these packages should not be many, currently we have ~32 opened FTBFS trackers according to autoconf-2.71, where the majority of them are just ignored by maintainers [1]. This can also be a possibility to remove unnecessary packages from Fedora. After merging the change, there should be a mechanism for validating. From my perspective, it is effective to rebuild dependent packages (~1700 packages). After the rebuild, there should not be many FTBFS packages, but according to the change there will be some. There was enough time (~6 months) for the maintainers to prepare for this change.
If there are any concerns or other opinions about the steps after merging the change, please share your thoughts and we can discuss them here.
Thanks very much!
Regards,
Ondrej
