Given our current strategy of minimal binaries per platforms, running on FreeBSD 7+ without compat6x means abandoning FreeBSD 6, which some of our customers still use, so this isn't an attractive option at the moment.
As for ZFS, I, and we, appreciate the ER. It will help product management the most if you can convey why running on ZFS is important to you -- what are the business issues etc. Realistically you can already defeat the check with some minor hacking, but it means you are in a configuration which is not currently undergoing any testing.
ZFS specifically, as opposed to other filesystems, does have some issues with high-io applications, especially high I/O and high computation tasks such as Splunk. Since ZFS performs checksum verification for all reads and writes, this means high I/O can reduce CPU avaialbility, for many Splunk loads causing a significant reduction in overall performance. This reduces, to some extent, the attraction of spending a good deal of effort in verifying and qualifying that platform.
That said, please do tell us why it is important to do that work, via the ER channel.
