I will personally port the plugin to QGIS 3 as soon as I can and
continue to make it available (I could even make a PR and propose it
as a tool that comes out of the box with Processing), this because
anyway has proven a valuable tool for less advanced users that are in
the situation to create copies of their data with a new CRS and with a
datum transformation involved.
Other than this anything that makes easier handling datum
transformations in QGIS is welcome.
