Perhaps you're imagining that filters will be added willy-nilly, without a thought to long-term usability and the possibility of bloat.
Well, who guarantees filters will not be added willy-nilly? Or that a newly added filter won't interact badly with an existing one? Since the xz format allows many changes, I assume some changes will be made. Else its modifiability would be a waste.
Can you name archiver formats that specify subblock-like filters?
Yes, RAR. See the file headers.hpp in unrar source.
lzip 1.5 supports the version 1 file format, but it does not support the sync flush marker, which lzip 1.7 and later support. Look for "Sync Flush marker" in decoder.cc. Equivalent code is not present in 1.5.
This is not exactly a format change. I added that marker from lzlib for interoperability with lzlib, but lzip itself does not use the "Sync Flush marker" for anything.
