Both are true, now being very careful regarding software patents usually pays a lot.

And even if for now lzo or lz4 are better, we may find something still better than what we think is now. In short, I still tend to think that the right answer would be to have a dedicated set of hooks and let people play with the compression algorithms they want (statement stands for FPW compression as well, but that's separate than the multivariate statistics patch).
