Note that r.compress -u still compresses null files if GRASS_COMPRESS_NULLS=1. OK?

You mean that the null files are ignored with -u?

Yes, the -u flag does not affect null file compression.
On library level: when opening a new raster with Rast_open_new_uncompressed(), null files are still compressed if GRASS_COMPRESS_NULLS=1. Maybe it would be more logical to not compress null files with Rast_open_new_uncompressed().

From a user's point of view it would be beautiful to have the null file un/compression done according to the use of r.compress with/-out -u. Probably for 7.4?
Note:
See TracTickets
for help on using tickets.
Replying to neteler:
Apparently a bug in the rasterlib when NULLs are compressed, but not data. Should be fixed in r71448,50 (trunk, relbr72).
