Hi,
I incline to clean up the data as a default. The module should behave in a
user-friendly way therefore expected behavior should be the default one.
I guess that most users would expect to import the data in topologically
correct format. If the topology is wrong, a user can get totally misleading
results (wrongly assuming they are correct) from various vector modules
which is not very nice.

I would not make it the default. You cannot be sure that users want to
clean in the same way you do, so better to provide it as an
(well-documented) option.
