I'm probably a little late to comment, but here's my two cents' worth.

My laptop, which runs Devuan, is a heavily-used Samsung N150p which was
purchased from a friend for $40 USD, it also runs an Intel Atom processor
(although I prefer ARM), and it is predominantly 32-bit:

$ uname -a
Linux MB 3.16.0-4-686-pae #1 SMP Debian 3.16.39-1 (2016-12-30) i686 GNU/Linux

$ lshw
...
product: Intel(R) Atom(TM) CPU N450 @ 1.66GHz
vendor: Intel Corp.
physical id: 1
bus info: cpu@0
version: 6.12.10
serial: 0001-06CA-0000-0000-0000-0000
size: 1667MHz
capacity: 1667MHz
width: 64 bits
...

There is 2GB of RAM, and anything that uses "hardware acceleration"
grinds to a halt and can take minutes between screen refreshes.

$ free -h
             total       used       free     shared    buffers     cached
Mem:          2.0G       186M       1.8G       460K        28M        90M
-/+ buffers/cache:        67M       1.9G
Swap:         9.3G         0B       9.3G


I love my laptop, however, because the whole thing is ~8x11 inches, and
can be brought everywhere. I use it for programming from the termninal;
there is no "greeter" installed and it boots straight to getty. I use
a text-mode editor (which will not be mentioned to avoid flames (it's
not emacs ;P)) and that's it.

While the Atom processor DOES support 64-bit computing, it seems that
every instruction takes twice as long -- it takes 30 minutes to boot a
Tails live image. (Yes, I know about heads; it didn't boot.)

For people like me, the "latest and greatest" features are simply useless
overhead that makes things bigger, slower, heavier, hotter, and/or use
more electricity.

With all due respect, I would appreciate it if 32-bit processors would
continue to be supported. (ARM too, I'll finish my Raspberry PI 3B-based
laptop Real Soon Now! (Maybe next weekend... next month...))

Of course, there is absolutely nothing stopping me from saying it has.

Use common sense and most of your "security" becomes redundant.
