Migration from jquery.ajax $.ajaxSettings.traditional = true. How remove [] from params

[rafaelpereznajera]

Migrating from jquery ajax to ember-fetch:

When the app sends queryParams that is type: 'array'.
For example: b = [ 1 , 2 , 3 ]
In jquery ajax settings when traditional = true -> b=1&b=2&b=3
In jquery ajax settings when traditional = false -> b[]=1&b[]=2&b[]=3

In ember-fetch, there is no option traditional = true, always send params with []

Is there an option that I am missing ?
