Moreover, many of journal reviewers may never worked with the low-resolution data and understand importance of every A^3 counts. It is not clear to me how to report the resolution of data when it is 3A in one direction, 3.5A in another and 5A in the third.

In the very low resolution world of SAXS, the whole idea of resolution is problematic. One can quote the minimum d-spacing (maximum angle) measured, but it is not a useful number to report. People are much more concerned about the quality of the data at maximum d-spacing (lowest angle). Perhaps very low-resolution crystallography is starting to enter this regime as well in which resolution concerns are turned upside down.
Granted, SAXS is a heavily averaged experiment which can densely sample q space, but which does not even attempt to produce density.
But the point I think that is appreciated in the SAXS community, is that the connection between extent of data in reciprocal space and model features is not simple.
