Re: [csswg-drafts] [css-grid] What happens with grid line names when dropping tracks

I'm not sure what you mean by "will become".
I'm assuming that you're talking about the _resolved value_ for these 
properties.
https://drafts.csswg.org/css-grid/#resolved-track-list

When there are zero tracks Firefox returns 'none' as the resolved 
value.
Other than that edge case, we essentially merge the line names with 
the names on both sides of the dropped track and then remove any 
duplicates. So for the example you give, "[a] repeat(auto-fit,[b] 10px
 [c]) [d]", the resolved value is "[a b] 10px [c d]" when there is one
 item, the resolved value is "[a b] 10px [c b] 10px [c d]" when there 
are two items etc.

I think this is the result you're suggesting, right?
