Also, take a look here:
> Additionally, a voluntary approach may have had the advantage of having a wider scope, compared to the regulatory option, for example, it may have covered both ends of the charging cable.
>However, given the unsatisfactory outcome so far of the progress in the voluntary option, the Commission will shortly launch a study to assess costs and benefits of different options, including the regulatory one.
This seems to say fairly clearly that only a voluntary option would cover both ends of the cable. Then it says they are looking at the regulatory option instead of the voluntary option. It doesn’t seem to contemplate a non-voluntary regulation covering both ends of the cable.
I don’t think I’m being pedantic or obtuse here, just reading the doc plainly.
