I definitely understand why he doesn't want to merge it in and risk potential litigation from Oracle, but I think he's kind of wrong about the rest of what he says.
I don't know what people on Solaris use, but I'm pretty sure everyone in the Linux and BSD community is running OpenZFS, which does get frequent updates and has been pretty stable as a kernel module for quite awhile. My main server in my house is running a RAID-Z2 on Linux and has been for more than six years, and I haven't really had any issues. I run scrubs regularly and things seem to work just fine.
I do wish that Oracle would give written permission to let Linux include it into the kernel, since I think it would make it easier to run ZFS on root (which I don't bother with, I just use btrfs on root and that's fine for single-drive systems, like a laptop).
