While all this may make sense, I'm missing some more reasoning
behind the differences between X.org and glibc.

This change also looks strange:

-    'ka_ge':                                'ka_GE.GEORGIAN-ACADEMY',
+    'ka_ge':                                'ka_GE.GEORGIAN_PS',
     'ka_ge.georgianacademy':                'ka_GE.GEORGIAN-ACADEMY',
     'ka_ge.georgianps':                     'ka_GE.GEORGIAN-PS',
     'ka_ge.georgianrs':                     'ka_GE.GEORGIAN-ACADEMY',

Why is GEORGIAN_PS written with an underscore whereas the other
mappings use dashes ?

Or this one:

-    'fi_fi':                                'fi_FI.ISO8859-15',
+    'fi_fi':                                'fi_FI.ISO8859-1',

Why would a locale switch away from an encoding having
the Euro sign to one without it ?

Or why is this latin variant removed:

-    'nan_tw@latin':                         'nan_TW.UTF-8@latin',

Why should Russians switch back to ISO ?

-    'ru_ru':                                'ru_RU.UTF-8',
+    'ru_ru':                                'ru_RU.ISO8859-5',

or from ISO to KOI ?

-    'russian':                              'ru_RU.ISO8859-5',
+    'russian':                              'ru_RU.KOI8-R',

The more I look at these changes, the more I believe we
should not simply take everything we find in the files
for granted. They obviously both have bugs.

It's not a table of exceptions, it's a table mapping commonly
used locale settings to ones which the lib C understands :-)

But regardless, I checked the code and it is already
smart enough to convert lib C incompatible spellings such
as "utf8" to "UTF-8", so these entries can indeed be
removed, but only if the locale is otherwise listed.

In some cases, it's probably better to drop the ".utf8"
to have more generic mappings, e.g.

+    'bhb_in.utf8':                          'bhb_IN.UTF-8',

or

     'de_li.utf8':                           'de_LI.UTF-8',

though I'd expect that mapping to be:

     'de_li':                           'de_LI.ISO8859-1',

as for all other "de" entries.
