That would be definitely nice but I think that just like the nested grids problem I would make that multiple grids.

My proposal is much more like others css styles like padding and margin.

padding: 0px 5px; === padding 0px 5px 0px 5px;

Subject: Re: grid-gap as repeating pattern

I was thinking of something along the lines(not exactly a pattern to repeat) because I couldn't find a way to do variable grid gaps.

Use case - having different gap between cells at different rows.

Example - Building a macbook pro keyboard layout with CSS. The top function keys row has narrower grid gap than the other keys beneath it. 

I'll be able to reply with much more detailed explanatiom when I am on a laptop.

It would be amazing if the following was possible with the grid-column-gap and grid-row-gap.

grid-row-gap: 0px 5px;

This means that the gap on row boundary 2,4,6... is 0px and on the row boundary 3,5,7... is 5px.

This can be scaled up as many values as wanted. The reason that boundary 1 is skipped is because it is not an inner boundary.
