 > A better description is directly from the patch/pull-request ([3]):

 >   Traditionally, ICU4C has defined its own `FALSE`=0 / `TRUE`=1 macros for use with `UBool`.
 >   Starting with ICU 68 (2020q4), we no longer define these in public header files
 >   (unless `U_DEFINE_FALSE_AND_TRUE`=1),
 >   in order to avoid name collisions with code outside ICU defining enum constants and similar
 >   with these names.

 > and explains why it occurred just recently/since the icu bump to version
 > 68-1 ([4])...
