Torch.fx.symbolic_trace doesn't preserve module methods

Are module methods other than forward preserved? I expected scale to be there in the traced_mod.

import torch
import torch.fx

class MyModule(torch.nn.Module):
    def __init__(self):
        super().__init__()
        self.linear = torch.nn.Linear(512, 512)

    def forward(self, x):
        x = self.linear(x)
        x = torch.relu(x)
        return x

    def scale(self, x):
        return x * 2

mod = MyModule()

traced_mod = torch.fx.symbolic_trace(mod)

x = torch.randn(1, 512)

orig_out = mod.scale(x)

traced_out = traced_mod.scale(x)
"""
