Multiple options besides Wolftooth:

FWIW before I sold my tandem which had a DA long reach 10spd RD I used a Wolftooth to cover an 11-36 10spd cassette on the bike with a 50/39/30 cw
and it shifted fine. RD was ~2007 model. I looked at the setup without the Wolftooth, fussed with the B screw and finally decided to go with the extender,
though the RD cage did just clear the cassette without the extender.
FWIW Shimano road RD have had built in extenders which is accomplished by moving the pivot point outboard of the RD
mounting point on the frame for the past 4-5 yrs. Started with DA
and moved to Ultegra with the 8000 series and 105 7000 series. The ATB RD had this years before styled as "Shadow".
