Yes, if it ever switches to a fullscreen state.

No, the window would have to be in the fullscreen state in order for
checks on window decorations or window size to even have the
possibility of breaking the spec.  Those checks in src/stack.c were
basically meant as a workaround to help legacy applications who don't
correctly put themselves into fullscreen mode still get into that
mode.  Yes, the checks appeared buggy (and we will fix them if I can
find some time to verify), but it shouldn't adversely affect any well
behaving application.

Feel free to point to anywhere in the ICCCM or EWMH that says so.  Of
course apps can be resized programmatically -- because the
not-resizable hints can be modified programmatically.  I disagree with
allowing the app or other utilities to modify the size of an
unresizable window unless the unresizable'ness is first modified.
