Although that is an alternative to have in reserve, should circumstances require it, you are leaving quite a lot in the hands of fate as well as ignoring basic QRH drills.

Once recognised, UAS is relatively straightforward to deal with in the proscribed manner and once under control, allows things like landing performance, fuel dumping, approach planning and other minor details to be considered. There is also the chance that in running the checklists you might manage to identify some correct indications and change air data sources, such that you can continue the flight. Another factor is that UAS can be quite subtle, so it takes a while to recognise; at that point you could be a long way from where you thought you were, so current groundspeed, attitude, etc. are not good datums to base a recovery on.

“Roll into a circuit and land” is very rarely an optimal solution to most problems encountered in modern commercial aviation. If there’s a fire inside your aeroplane that won’t go out, sure, but for pretty much everything else, getting away from the ground and having a good think/discussion about how/when to get back onto it is the safest course of action.
