Yes it does, perhaps you misunderstand the answer?  Let me rephrase:
because it is faster to bundle in some circumstances, and in some
circumstances significantly faster than any other possible optimizations.

see my reply to your other message.  You're wrong, it's not possible to
reliably bundle files containing namespace/import statements as
currently implemented.

Sorry, your last statement does not add anything to the debate but
noise.  We are discussing the multiple namespaces per file patch.  If
you'd like to discuss which programming language to use or talk about
hypothetical programming techniques, try php-general or IRC.
