Ah, I forgot that systemd actually needs it. So I guess there is currently no way to use systemd on 32-bit machines that are meant to survive 2038, regardless of whether systemd and glibc are built with a 64-bit time_t or not, right?

Is there perhaps a way to change the logic in a way that it does not depend on the current time but instead depends on a property of the RTC device itself, so we make systems break immediately instead of by surprise in 2038?

Are you seriously suggesting to cause regressions on systems where the RTC can send the kernel's timekeeping back to the early 1900s, rather than printing a big fat warning message in the kernel log?
