stlport iostreams

I just ran across this comment in tools/stlport.jam:

# The problem: how to request to use host compiler's iostreams?
#
# Solution 1: Global 'stlport-iostream' feature.
# That's ugly. Subfeature make more sense for stlport-specific thing.
# Solution 2: Use subfeature with two values, one of which ("use STLPort iostream")
# is default.
# The problem is that such subfeature will appear in target paths, and that's ugly
# Solution 3: Use optional subfeature with only one value.

I find this really strange, since default values of features and
subfeatures are *not* supposed to show up in target paths. It seems
like Solution 2 should work just fine, unless the subfeature is
"symmetric".
