Is it possible to implement some support for old functionality like
bitbake -c clean -b path.to.recipe.with.BBCLASSEXTEND.bb

Now it fails with error like this:
bitbake@jama ~/build.dev.shr.gta $ bitbake -c clean -b ../dev/recipes/libxml/libxml2_2.7.6.bb
ERROR: Parsing error data_fn virtual:native:/OE/dev/recipes/libxml/libxml2_2.7.6.bb and fn /OE/dev/recipes/libxml/libxml2_2.7.6.bb don't match

-b was usefull for quick rebuild of modified recipe (ie to rebuild it in workdir
after updating for new staging or BBCLASSEXTEND to see if everything is "the same")

It's really hard to implement something like prefixing -b path with "virtual:native:"
for native variant and use old behavior (clean non-native version) without virtual: prefix)?
Or just nobody cared yet? In this case I would check what can be done.
