Re: [csswg-drafts] [css-grid] Resolved values of grid-template-rows/columns don't round-trip (#4475)

Agenda+ to discuss whatever needs to happen to make the resolved value of grid-template-rows/columns actually be a valid value for grid-template-rows/columns, either:

1. clarify wording to not imply that the implicit grid is serialized as part of the value, going against all implementations
2. add sufficient new features to grid-template-rows/columns to allow them to size implicit tracks too, and change the serialization of the resolved values to use those features, again going against all implementations.

We cannot stick with what we have today, where all implementations agree on serializating g-t-r/c as a value that is not valid for those properties (the serialization is accidentally valid, but as a *different* g-t-r/c value, not corresponding to the used value that's supposed to be serializing).

Because both possibilities require all implementations to change, and (2) is actually rather complicated and of fairly minimal value I think, I strongly support (1).
