It was very common for another designer to take a complete assembly and remove individual components and replace them with customer requests. When constraints are done properly (using datum axis and planes when possible) this is a quick task. When done through the method you describe it makes other people's days more difficult.
To the OP, re-constrain the whole thing, if nothing else it is 15 minutes of good practice.

I would agree for any assemblies you are likely to customize or modify.
The vexpro 3 CIM Ball Shifter comes in as over 60 individual parts and contains 3 subassemblies down to the balls in the shifter. Regardless of the gearing spread used, the mounting points and overall size of the gearbox does not change except for two external gears. I would be impressed to see it fully constrained by a student in 15 minutes. Half the time I delete all the internal gears to make it load faster in the assembly.
The sonic shifter has fewer parts and could probably be constrained in 15 minutes. It is good practice, especially if you haven't physically assembled one before.
Unfortunately in FRC I'm often using the CAD as an easy mounting pattern reference.
