OK, I installed it into emacs-28 with the following reworded NEWS item:

** There is a new configure option '--disable-year2038' to cause
Emacs to use only 32-bit time_t on platforms that have both 32- and
64-bit time_t.  This may help link Emacs to a library with ABI
requiring traditional 32-bit time_t.  This option currently affects
only 32-bit ARM and x86 running GNU/Linux with glibc 2.34 and later.
Emacs now defaults to 64-bit time_t on these platforms.

Yes, there will surely be some glitches, and not just on MS-Windows. 
I'll send a brief word of warning to emacs-devel.
