Python 3.6 client support

I went to github and looked at the python client generator code and started moving the version tag back one release at a time until I found the release (6.1.0) that last supported python 3.6 (2022). I pulled this release and built it and generated a python client from my spec. 

Now I have to ask - Rather than generating standard python 3.4+ Enum classes:

from enum import Enum
class NetIdEnum(Enum):
        RDMA = "RDMA"
        RDMA6 = "RDMA6"
        TCP = "TCP"
        TCP6 = "TCP6"

Or, if scoping is a concern:

from enum import Enum
class QualifiedAddressView(NormalMode):
    class NetIdEnum(Enum):
        RDMA = "RDMA"
        RDMA6 = "RDMA6"
        TCP = "TCP"
        TCP6 = "TCP6"

it does this:

class QualifiedAddressView(ModelNormal):
...
    allowed_values = {
        ('net_id',): {
            'RDMA': "RDMA",
            'RDMA6': "RDMA6",
            'TCP': "TCP",
            'TCP6': "TCP6",
        },
    }

which makes for pretty unwieldy client usage:

if QualifiedAddressView.allowed_values[('net_id',)]['RDMA'] == "RDMA":
    print("This is an RDMA type")

rather than the much simpler:

# Checking the value of net_id
if address.net_id == QualifiedAddressView.NetIdEnum.RDMA:
    print("This address uses RDMA protocol")

Can anyone expound on why this choice was made?
