modulepath layout and version number in output directories

[Sahoo]

According to [1], for an input source structure like:
src/m1/module-info.jar #let's say m1's version is 1.0 in module-info.java
src/m1/...
src/m2/module-info.java #let's m2's version is 2.0 in module-info.java
src/m2/...

javac -d modules -modulepath modules `find src -name "*.java"` produces 
following output directory structure:

modules/m1/module-info.class
modules/m1/...
modules/m2/module-info.class
modules/m2/...

Since every module has always got a version (if not explictly specified, 
there is always a default version), is there not a benefit in encoding 
the version number in output directory structure? e.g., how about the 
output directory structure looking like:
modules/m1/1.0/module-info.class
modules/m1/1.0/...
modules/m2/2.0/module-info.class
modules/m2/2.0/...

The example in [1] that uses multiple module versions recommends 
encoding version number in src directory structure (e.g., src/m1-1.0, 
src/m2-2.0, etc), but I am not so sure how practical it is. How often do 
we find version number encoded in svn or hg or cvs directory name?

Thanks,
Sahoo
