I don't think there should be much trouble in this department. Unless
one is literally trying to download megabytes of data or millions of
items from a query (which we are working on solution for, but not yet)
the size of the string doesn't matter much and there would probably be
no noticeable difference between 400 and 2K strings for most queries I
can think of. Searching within such strings won't probably work very
well but that's not the intent anyway, as I understand.

The only thing I can think of is that we now both store the whole item
as huge blob in the DB (and consequently load it in memory) so if we had
a lot of huge strings it may have negative performance impact. But I
don't think changing a property that is usually one per item from 400
bytes to 2K would change anything.
