Leave MPLM at station ?

I realise that the MPLM isn't "space rated" for long duration.

But with the grounding of the shuttle, possibly for very long (indefinitely
?), would they consider leaving Rafaello at the station during STS 114 so that
the crews would have sufficient stowage space and not fill the station living
quarters with tons of supplies and rubbish ?

I realise that the hatch would probably have to remain closed when crew aren't
moving stuff in /out of the MPLM due to lack of sufficient debris shielding,
but it would still be greatly useful to the crews for stowage.

Since the MPLMs become totally useless by 2010, would it be a great loss to
leave one at the station even if it needs to be ditched later on ?


And now that the shuttle is apparently grounded, would there be pressure on
the europeans to bring ATV in sooner rather than later ? What is preventing
them from launching now ?
