#### Is your feature request related to a problem? Please describe.
No.

#### Describe the solution you'd like
#4734 Changed the entire behavior of the params serializer, breaking using any custom functionality on the consumer side. Add a boolean switch to mimic pre 1.x behavior (default is false) and send the params directly to the encode function

#### Describe alternatives you've considered
Tried working with new solution; it did not pan out well and led to more bugs with our requests
