OpenZFS on OS X

Looking at downloads in viewtopic.php?f=20&t=3619, it's interesting to notice that 10.9 through 10.12 have about the same number of users, making sense for supporting them all.
I mean: it doesn't make much sense dropping Mavericks support (Downloaded 76 times) when Yosemite (Downloaded 54 times) and El.Capitan (Downloaded 71 times) seem to have less users... and Sierra little more (Downloaded 78 times).

2.1.0 issues not being solved for Mavericks yet, I hope they will but of course, I can understand the difficulty of maintaining 10 builds, each one with their own issues and keeping support active only for 10.13+ would also make sense, considering those stats.
My two cents.

I build for whatever people ask for. Although I haven't done a 32bit build in forever. I didn't do 10.8 as I lost the VM, but probably could still if people were desperate.
