SVN is still the master repository and Git the mirror. I wanted to leave
enough time to the Apache infrastructure team to settle down their work
related to Git support with other projects. I didn't checked their
status lately. Maybe Chris Mattmann would know more.

An alternative which may be nice to explore would be whether we could
use Apache Calcite for managing the SQL interpretation part. Ideally not
only for Shapefile, but some other data stores too.
One thing that would be nice to adjust before a sis-shapefile release
would be to uniformize (at least partially) the API with other data
stores. A common API proposal has been submitted in [1] but is likely to
evolve.
