I did a man xterm, and turned up the following:

"Most of the xterm options are actually parsed by the X Toolkit, which
sets resource values.  Xterm provides the X Toolkit with a table of
options.  A few of these are marked, telling the X  Toolkit  to
ignore  them  (-help, -version, -class, -e, and -into).  After the X
Toolkit has parsed the command-line parameters, it removes those which
it handles, leaving the specially-marked parameters for xterm to
handle."

"-fn font
               This option specifies the font to be used for displaying
               normal text.  The corresponding resource name is font.
               The resource value default is fixed."

So, in all likelihood, the font named fixed is set by X.  That
probably means the X definition of fixed changed between F21 and F22.
Since X is undergoing major construction because of wayland, that might
make sense.

This also could explain why the command line version is so minimal -
xterm gets no options.  In the gui version, there are probably default X
options that add all the gui goodies.
