The EPSG terms of use allows such conversions provided that data are numerically equivalent. The proj.db file in PROJ 6 is (to my knowledge) compliant with this condition, which is a very good thing. On the "doesn't attribute it to the EPSG dataset" part, in my understanding we are attributing those definitions to EPSG dataset as long as we use the "EPSG" authority name in "EPSG::4326", or that the documentation claims to support EPSG codes. But since PROJ 6 is compliant, this is not a problem. The issue is that EPSG wants all users downstream to continue to comply to those conditions, which is why they want us to inform users. I'm not a lawyer neither, but my understanding of discussions I have seen at Apache and at OGC (including with IOGP staffs) is that packaging the same data in a different format does not erase EPSG ownership on those data. Of course this is only my point of view. But maybe a verification by someone more familiar than me on legal topics would be desirable.
