From a developers point of view certainly not. From a users point of view, IMO, yes.

Having the user scenario in mind which I wanted to address with this patch 'opening - destructive editing in place - saving' is identical to 'opening - gegl op editing - saving - loosing the gegl graph'.

Whereas if an image has more than one layer it's far more evident that one wants to work non-destructive. So the criterion 'one layer nonXCF' is IMO still suitable to allow a destructive workflow.

Anyway, you can't totally prevent users from data loss as long as you support non-XCF formats and offer Export / Overwrite.

IMO it's all about finding a trade-off between 'restrictions to prevent data loss' and 'allowing common user scenarios'.
