Just ran some tests on yesterdays Zesty 64bit ISO on a Virtual Box VM set for
1GB ram.
Even with the slight performance loss on running on a VM, I was working
acceptably with File manager, Firefox (two tabs) Gnome software, terminal and
Calc (slight delay on Calc straight after swapping from Software to Calc, but
after a few second that stopped.
But looking at 'Top' Gnome software and Calc were the biggest memory uses.
I think that's just because they map a lot of files, it's
not real memory usage.
Instead of "top", use e.g. this tool:
http://packages.ubuntu.com/yakkety/smem
https://www.selenic.com/smem/
And look at the PSS information.
(PSS information changes depending on how many apps are running
as unlike RSS & VmSize, it takes memory sharing into account.)
I usually do my iso testing on VM's with 2GB of ram, and while you do get a much
better perforamce with 2, those people who will be using older hardware with
1GB, would know not to expect to run loads of apps at once and expect a fluid
performance.
Most of the apps are fine in 1GB even if you run a lot of them.
Only things like www-browsers, LibreOffice and manipulating large images
e.g. in Gimp are really memory hungry.
(Real-time video editing is already otherwise too demanding for
these machines. :-))

Canonical developers do not benchmark or run any regular testing on
Xubuntu; this is not their work. Whether they do that for Ubuntu, I
don't know. To be exact, Canonical "only" offers the infrastructure for
Xubuntu.
If there are volunteers who are willing to set up a benchmarking
process, run the benchmarks and ideally work on improving code in order
to succeed better in the benchmarks, we're totally welcoming them.
I haven't run Xubuntu on low-memory (virtual) machines lately, so I have
no idea what the usability is below 2GB RAM, but I'm pretty sure it's
usable.
Setting the minimum any higher than the "acceptable" doesn't make any
sense. If we consider 1GB memory bringing an acceptable experience but
set the minimum to 2GB, we could potentially turn out people with just
1GB memory – just by telling the minimum is 2GB. In other words, by
setting the minimum too high, we would put Xubuntu out of reach for some
users only *socially* (as technically they could still run Xubuntu).
This is why the minimum should be as low as possible.
Ultimately smoothness and acceptable responsiveness is very subjective;
this is why we have minimum and recommended. Maybe you're saying
recommended should be 2GB; if the minimum is 1GB, this sounds sensible.

Do Canonical developers routinely benchmark xubuntu (and other
flavors) against a Windows or Mac OSX version? In other words, should
the recommended xubuntu RAM size be sufficient to run programs at a
speed similar to the memory-hungry programs on a Windows or Mac box
(Office, Internet Exploder, etc.)? For xubuntu, I'm thinking of the
Firefox, Thunderbird, and LibreOffice triad in particular. As
flocculant wrote, 1024 MB should be the very minimum. I would say
2048 MB should be the minimum, but that would place xubuntu out of the
reach of many computer users globally.

What is comfortable is definitely subjective, but I think the
minimum
system requirements should reflect an environment where you run one
resource-intensive application at a time at most. Or in other words,
you shouldn't expect to be able to edit high quality video and watch
another at the same time smoothly with the minimum requirements.
However, you should be able to be somwhat productive with your work
with those resources.
