I think that the two-dot-name solution would be the way to go. This
would add more structure to the naming, and would make it easier to find
all modules doing stats.

Over time, the existing other modules could be renamed, but the original
modules could stay and just give a warning: "deprecated - use
r.statistics.whatever instead" and execute the correct module.
And then in the next major version, these could raise an error and not
execute the module, and finally just delete the original module.
