Perhaps, but the list of possibly usable defaults for Fedora is not very long.

ext3, ext4, xfs, btrfs for now, I'd say.

Anything that "popped up" last month is not going to be ready for primetime
for years.

That said, I'd love to see it easy to tweak the default from among the supported
anaconda filesystems via kickstart or boot-time option, vs. having to go into
the detailed custom storage setup screen.  "ext3 please" is a lot simpler request
than custom partitioning with volume managers, and today it's all rolled into
