I don't think this is really significant to be honest. All the cars where generally using less than the allotted fuel amount, so Mercedes can use more along with other teams but it will just underfuel by a similar percentage and maintain their advantage.
Eh, according to that AMuS article, Mercedes used the fact more fuel was going to be allowed as (one of the?) reason(s) to decide to not prioritize efficiency but rather go for 'max downforce', and so far, their path has worked in the races (I would agree with an argument they did not in fact have the best car everywhere but won on teamwork, but in Spain they surely were the best).
I am pretty sure that even last year, Honda had a problem with fuel, and surely in 2015,'16 the lack of late-race pace from Alonso would be explainable by that; also, someone made the FIA think that allowing (even) more fuel flow than already allowed since the 2017 changes, would increase competitiveness; combined with Horner often mentioning the fuel flow as an unneeded limit, Red Bull (or Honda) likely thought it would too.
For Ferrari and Mercedes engined teams you are likely right about underfuelling in many races in 2018, but I am not sure that Renault was always able to underfuel as much, and again, Honda very likely were not often able to.
