No, that is not the case.

We're currently in a phase where ubuntu-device-flash is still being used
but the future will be a new tool called ubuntu-image which will allow
you to create images in a much better way.

You can override the sanity check for the gadget names with setting
UBUNTU_DEVICE_FLASH_IGNORE_UNSTABLE_GADGET_DEFINITION=1 in the command
line you're executing. Didn't tested this but maybe Michael can comment
how this should work.
