I think such a flag is blessed.

That's not 100% correct. 
On save dialog the kNavSupportPackages has a difference. If you select a
package and hit the "save" button and this flag is off, you get the "you
can't select a folder" message. If it's on you get the (expected) "the
file already exists Replace/Cancel" message.

On open dialog WX currently only turns on kNavSupportPackages and the
dialog works excellent. It allows me to select package as files for
opening.

I'm not sure turning it on for all cases is the write thing. It depends
on it's interaction with kNavAllowOpenPackages.
I can assume it makes sense usually, but I can think of cases where you
won't want that.

Say I want the user to select a folder for something. But say I don't
want him to select package folders (all though sub-folders inside
packages are OK), I'd turn on the allowOpen flag and not the
supportPackages flag.

I think the 2 flags have different meaning and should be treated
differently in WX. I do think, thought, that using the proper default is
important.


Also, I would like to know if you'll be doing this, so I know not to do
it and submit a patch.
