Hi Ross,

Thanks for your feedback!

I didn't quite understand what you mean. As I know, if we add the the 
setting in manifest as below:
diff --git a/meta/recipes-devtools/python/python3/python3-manifest.json 
b/meta/recipes-devtools/python/python3/python3-manifest.json
index f922561..09c9199 100644

+            "core",

          ],
          "files": [

          ],
          "cached": []
      },

There comes below error:
ERROR: Nothing RPROVIDES 'python3-tk' (but 
/mybuild/layers/oe-core/meta/recipes-devtools/python/python3_3.5.6.bb 
RDEPENDS on or otherwise requires it)
NOTE: Runtime target 'python3-tk' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['python3-tk']
ERROR: Required build target 'python3' has no buildable providers.
Missing or unbuildable dependency chain was: ['python3', 'python3-tk']

That's to say, we still need to add some fix in 
meta/recipes-devtools/python/python3_3.5.6.bb. If so, it may be flexible 
and clear to directly to make the implement just as what I send in the RR.

Thanks,
