I don't quite understand where the reproducibility is broken ?
multi-threaded compression does not create a predictable reproducible archive (for xz/zstd).
Amin Vakil says that rebuilding his initrd (when updating kernel and/or modules) takes a lot of time and the final compression phase can be reduced by switching to lz4 or lzop. when you go from xz (which may be his case) to lzop, the difference is remarkable.
Sure, has nothing to do with reproducibility however.

hi,
change the COMPRESSION variable to lz4 ou lzop in your /etc/mkinitcpio.conf : it will considerably reduce the compression time.
And break reproducibility. Also, I wouldn't say considerably. Might be faster, but not leaps and bounds faster.
