Sometimes using serialization_alias would be better than using alias; this should be switchable

[GeorgeFischhof]

Is your feature request related to a problem? Please describe. No / depends on

Describe the solution you'd like create a switch to use serialization_alias instead of alias

Describe alternatives you've considered could not imagine alternatives

Additional context We would like to set value using original name (Pythonic), and therefore we would like to use serialization_alias to send appropriate data

Thanks, BR George
