This combo gives you about a ~25mm field of view, or 21mm in FF terms. Initial results seem better than good enough; maybe just a touch softer than the GF20-35mm f/4 but for sometime like me that barely uses that lens, I think it could be a more than adequate replacement.

Takes less than 30 seconds to mount even if you’ve got the hood + filter equipped, so not much worse than a lens change. Plus you don’t have an exposed sensor so it’s more ‘comfortable’ to do in wind/dust.
