Now that the Fedora 34 release is out the door, the Fedora project is
turning its attention to Fedora 35, which is currently scheduled
for release on October 26. One of the changes under consideration for
Fedora 35 is this
proposal allowing maintainers to choose whether to build their packages
with GCC or Clang. This policy change may give maintainers some welcome
flexibility, but it has not proved entirely popular in the Fedora
community.
