XKB lists quite a few keysyms as deprecated, but no keysyms we have
discussed here are affected.
I believe this indicates that they have never been used for another
mapping previously, but I haven't checked extensively.
However, it is also stated in xkbcommon-keysyms.h that:

This affects four of the keysyms mentioned:

> #define XKB_KEY_leftanglebracket 0x0abc /*(U+27E8 MATHEMATICAL LEFT ANGLE BRACKET)*/

> #define XKB_KEY_rightanglebracket 0x0abe /*(U+27E9 MATHEMATICAL RIGHT ANGLE BRACKET)*/
For two of these keysyms, I managed to find at least one application
that agrees with the current Emacs mapping that we now consider
changing:

See https://fossies.org/dox/putty-src/xkeysym_8c_source.html
I believe that we should consider carefully whether changing these two
mappings could introduce a regression for some use case, e.g.
PuTTY/ssh/emacs.
My proposed changes are attached.
