It would be very iseful.
I also propose the same for -o ssd option. USB drive may be used on different computers, and we need the way to specify it only once.
As for the options being per-file, I think having them as per subvolume defaults looks better: we can override the defaults on per-file basis while having reasonable defaults for each subvolume. (There may be also global per-pool defaults, which may be overriden by subvolumes).

I think that if the file is compressed it should remain compressed and = the "c"=20
attr should be used for that (both to report it and to set it).

There should be a way to specify *which* type of compression to use in = a=20

'-o ssd' definitely should go in the same basket.
