And the download page says that the current version of the legacy code
base (4.32.4) has support for detecting the new header.  From that src
there is this:

,----[ lzma-4.32.4/extra/magic/lzma.magic ]
| 0x00    ustring         \xFFLZMA\x00    lzma compressed data,
| >0x06   ubyte&0x10      0x00            single-block stream
| >0x06   ubyte&0x10      0x10            multi-block stream
`----

So it looks like they have it covered.

(For those looking at their git repos, I only find the magic file in
the legacy repo <git://ctrl.tukaani.org/lzma-utils-legacy.git> and not
in the new codebase <git://ctrl.tukaani.org/lzma-utils.git>.)
