What do you mean, "unable to"? It just doesn't.
Could it? Perhaps, if somebody wrote a patch.
Would the patch be accepted? Perhaps, if it didn't break something
else.
In the past, there was a silent guarantee that you could add
items to sys.path, and only later create the directories behind
these items. I don't know whether people rely on this guarantee.

I see. Out of curiosity: how much startup time was saved
when sys.path was explicitly stripped to only contain these
two zip files?
I would expect that importing 2500 modules takes *way*
more time than doing 10.000 failed opens.
