First, "svn export ." and "svn export URL" are very different, since
exporting from a WC by default exports the WORKING version of the files, not
the BASE version.

Regarding the checksumming, my opinion is that svn should not checksum here,
because to do so would be a crippling slowdown in many cases. (And
spontaneous filesystem corruption ought to be very rare)
