It is not an issue after the pkg_install-renovation merge.

LZMA itself is available under public domain. The biggest two issues
with the format (not the algorithm) is lack of checksum and lack of
proper header. It is a bit more expensive to decompress, but at least
for remote access the better compression rate should almost always
compensate for that.
