Meanwhile this has been fixed and the checks can be activated and will take effect immediately (with the next patch release 3.4.2 or any nightly build until then). There were also some severe issues which caused QGIS to crash which are already fixed in 3.4.1.

Thank you for your response, Matthias. I followed the instructions
(using 3.4.1) and got it to work.
I just noticed, that I am only able to force missing vertex errors.
When deliberately constructing gaps or overlaps those will not be
detected or QGIS crashes while checking the layers' topology. This
happened using a geopackage containing just 3 very simple polygons.
Would that be one of the issues being fixed by the upcoming 3.4.2
release?

Cheers
