All mass necessitated by an engine design should count as engine mass, eg shrouds, TVC hydraulic power or excess purge gas.
Raptors in production now have electric TVC, saving over a ton of hydraulics mass on booster.

Enabling engines to take the heat without shrouds might save over 10 tons, all things considered.
Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb.
Booster is purging all 33 engine shrouds in flight to prevent this.
