Sure. It does not matter much in real world because ability is never calculated
on SymbolFileOnDemand.

If the user sets a file and line breakpoint and a compile unit/supported file
is matched against the breakpoint file its parent module's SymbolFileOnDemand
will be hydrated before ParseLineTable() is called anyway so manual call
through is unnecessary.
I prefer to keep things not pass through by default to prevent any accidental
leaking.

Yes, we could. But I would like to keep all functions guarded by default unless
explicitly required by a hydration scenario to prevent any accidental leakage.

Ah, thanks! Bad auto replace for variable name.
