or platform metadata attached to the 'ns' form should be trated as "this
whole file is for this platform". This way, in src/py/blah.clj you'd have
^{:platform :python}
(ns blah)
...
(your code)
...
without relying on file extensions, directory structure or similar things.

I don't think it's "better", this two options are rather equivalent. The
only difference is that #+ would require new reader entities, while variant
with metadata leverages already existing clojure facilities.
Although, another thing is that it looks like metadata would be more
flexible; for example, one could write
^{:platform :jvm, :version "1.7"}
or maybe even something like
^{:platform :jvm, :version "[1.7,)", :implementation "sun"}
Of course, it's possible to make #+{:version ...} work, but then I don't
see how is it really differs from meta.
