It seems that the downgrade succeeded.

First mount:

[ 22.565053] bcachefs (dm-5): mounting version 1.4: (unknown version) opts=metadata_checksum=xxhash,data_checksum=xxhash,compression=lz4
[ 22.565686] bcachefs (dm-5): recovering from clean shutdown, journal seq 116996
[ 22.565717] bcachefs (dm-5): Version downgrade required:

[ 22.590487] bcachefs (dm-5): alloc_read... done
[ 22.597896] bcachefs (dm-5): stripes_read... done
[ 22.597930] bcachefs (dm-5): snapshots_read... done
[ 22.651106] bcachefs (dm-5): journal_replay... done
[ 22.651667] bcachefs (dm-5): resume_logged_ops... done
[ 22.651736] bcachefs (dm-5): going read-write

I wonder whether there was some text supposed to follow
"Version downgrade required:". The line feed was in the output.

Second mount:

[ 113.059224] bcachefs (dm-5): mounting version 1.3: rebalance_work opts=metadata_checksum=xxhash,data_checksum=xxhash,compression=lz4
