For what it's worth, there is a plan to allow data to be scrubbed so that
you can enable compression for extant data. No ETA, but it's on the roadmap.
In fact, I was recently reminded that I filed a bug on this in 2004:

I have an 800GB raidz2 zfs filesystem. It already has approx 142Gb of data.
Can I simply turn on compression at this point, or do you need to start
with compression
at the creation time? If I turn on compression now, what happens to the
existing data?
Thanks,
Neal

Yes. Nothing.

As I understand it, you can turn compression on and off at will.
Data will be written
