I strongly agree. Manually edited data should never be removed and
replaced automatically with a data import. Imported data likely
contains errors and omissions and does not contain additional
information (such as one way streets and POIs).

Instead, one should clean up the data by surveying and by using
validation tools such as "keep right" (keepright.ipax.at). To clean up
an area quickly, it may be useful to copy and paste missing data from
GeoBase, as it is generally fairly accurate (though it does not
include one way streets, and new roads built in the last few years
tend to be missing).
