Note checking this kind of errors on large multipolygons is not really 
that difficult.  For each of the big lakes that is a few dozen MB of 
download via overpass API and then a few seconds with osmium to 
assemble the multipolygon.  You can easily set this up to run on a 
daily basis to check a few lakes you want to keep an eye on.
