Correct me if I am wrong. Select paste and any rework repair material and process is part of design. The designer select all the devices in platform or generation format and draft BOM with termination finishing (with possible alternatives), and looked the key components thermal restriction requirement, and select required paste activity and possible rework times, temp. Solder wire or method. (Also may decide it just better to throw away). It also be the part of master plan for testing on what.% fault you want to repair and which field return forecast as a write offs. The question should be post to design group, not here.

Yes But,
If you buy everything from one manufacturer and there is a problem do you
really expect them to say:
"Yes, It is my problems, I will fix it." ?
If you think that would you like to buy a big bridge in New York City? :-)
If you can get what you need at a reasonable price from a single supplier
go for it. But various real world issues seldom make that possible.

Not only that, but it is inevitable that manufacturer X will blame the
product of manufacturer Y, should you ever run into any trouble.
