Yes. It makes sense and it is easy to implement.

But will it be compatible with 'svn commit' which has the same option?

We have to make sure that end users will not get confused with --depth's
depth level and
--include-externals' depth level. Our documentation should help for
users to understand
all of the following cases.

$ svn list --depth=immediates --include-externals=immediates
$ svn list --depth=immediates --include-externals
$ svn list --depth=infinity --include-externals=immediates
$ svn list --depth=infinity --include-externals
$ svn list --depth=files --include-externals=immediates
$ svn list --depth=files --include-externals

Thanks & Regards,
Vijayaguru

P.S: We can even avoid infinite recursion problem (when an svn:external
directly or
indirectly includes its parent) with 'svn list
--include-externals=immediates'.
