I don't think so.  fsck doesn't do anything that may involve linking
stuff into lost+found until phase 2 (Check Pathnames) and perhaps later
(such as phase 3, Check Connectivity); I think all recoverable blocks
should be found during phase 1 (Check Blocks and Sizes).

There *is* the danger that if the filesystem is absolutely full to the
top, there may not be any free space to create or extend lost+found.
But that is just as true of precreated lost+founds, though perhaps less
so since they are created with enough space to hold lots of entries.
