Indeed, users would expect the new uses of "as" to behave as the previous
ones. The problem is that "with" and "except" do things differently:
In [*1*]: *import* *os*
In [*2*]: *with* open(os.path.expanduser('~/tmp/xx')) *as* f:
...: *pass*
...:
In [*3*]: print(f)
<_io.TextIOWrapper name='/Users/apalala/tmp/xx' mode='r' encoding='UTF-8'>
In [*4*]: *try*:
...: print('ok')
...: *raise* *Exception*()
...: *except* *Exception* *as* e:
...: *pass*
...:
In [*5*]: print(e)

I don't take that as a challenge. It would be good to have different, maybe
somewhat competing PEPs. It's been done before.
