There was some concern from lifeless around recreating package-style dependencies in dib with element-provides/element-deps, in particular a suggestion that meta-elements are not desirable[1] (I hope I am paraphrasing you correctly Rob).

That said, this is exactly the reason that element-provides was brought in, so that the definition of the image could have "mysql" as an element, but that the DIB_*_EXTRA_ARGS variable would provide the correct one, which would then list itself as providing mysql.

This would not prevent the sharing of common code through a differently-named element, such as mysql-common.
