Ten years ago, in commit 6d4acb0e3a, these four keysyms were added
to support new compose sequences that then could be typed with the
newish German T3 layout -- or at least, that was the intention.
The commit was in response to https://bugs.freedesktop.org/62189,
right before I retracted the patch after learning that there are no
precomposed characters that use those four symbols as diacritics.
The commit should have been reverted then, but... it lingered and
was forgotten. No layout in xkeyboard-config uses these symbols
(obviously, as they serve no purpose) and meanwhile the T3 layout
itself has become obsolete [1], so... it's time to clean up.

"die Belegung T3 wird nicht mehr definiert, da die Erfahrung gezeigt
hat, dass eine solche Tastatur ohnehin nicht produziert wird"

This package provides the headers and specification documents defining
the core protocol and (many) extensions for the X Window System. The
extensions are those common among servers descended from X11R7. It
also includes a number of headers that aren't purely protocol related,
but are depended upon by many other X Window System packages to provide
common definitions and porting layer.
Though the protocol specifications herein are authoritative, the
content of the headers is bound by compatibility constraints with older
versions of the X11 suite. If you are looking for a machine-readable
protocol description suitable for code generation or use in new
projects, please refer to the XCB project:
The XF86keysym.h header file needs updating whenever the Linux kernel
adds a new keycode to linux/input-event-codes.h. See the comment in
include/X11/XF86keysym.h for details on the format.
The steps to update the file are:
if the kernel release did not add new KEY_FOO defines, no work is
required
ensure that libevdev has been updated to the new kernel headers. This may
require installing libevdev from git.
run scripts/keysym-generator.py to add new keysyms. See the --help
output for the correct invocation.
verify that the format for any keys added by this script is correct and
that the keys need to be mapped. Where a key code should not get a new
define or is already defined otherwise, comment the line.
file a merge request with the new changes
notify the xkeyboard-config maintainers that updates are needed
Note that any #define added immediately becomes API. Due diligence is
recommended.
