That is true.  Thing is, I've learned how to manage LVM even with
encrypted data.  I've also learned how to expand storage without losing
data or getting confused about what I'm doing.  To me, using LVM is
pretty easy given the notes I have for the tasks I do most often.

It's not that I want to compile things, it's that I want to use things
I'm already really familiar with.  If I bought a Raspberry Pi and built
a NAS with it, I don't care if I compile the software on it or not as
long as it has the software I need or I can install what I need.  From
what I've read, compiling on a Raspberry isn't much fun.  It's very time
consuming. Having a OS, binary one at that, that is Linux based is a big
plus.  I can run LVM, cryptsetup and such in likely every Linux distro
out there and get the same result as on my Gentoo box.  Switching to
BSD, using ZFS, means I have to learn a whole new set of tools and
methods.  I had enough fun learning LVM and I don't think LVM is going
to die anytime soon.  It should be around for the foreseeable future. 
As it is, even now, I still don't get how ZFS works.  I just followed a
guide to get it working, sort of.  It's still not encrypted.  Figuring
that out is next.  That should be fun. 

My network card is out for delivery.  A few days late but better than
never I guess.  I'll see if the drivers needed for it are available as
modules or not.  I suspect they are tho based on info in this thread.
