'Professional manner' - that's a deep hole to fall into. I think we all have seen what some consider professional work to be substandard.
Doing the HI it wouldn't be up to me to decide whether or not it is correct within manuf. standards and spec.'s, unless of course the client wanted to hire me separately to investigate and determine.
However, back to what you are probably asking ... if a long 2x4 bridge had been drilled and bolted to span the gap; if there seemed to be sufficient rigidity/compression I would probably write it up as repaired and recommend attempting to determine manuf. of truss and what their recommendations are.
2x4 with 2-3" overlap and drywall screws would not be acceptable to me but I'm sure Joe DIY would think it was done in a 'professional manner'.
