Sometimes that the best option, sometimes it's a hack. Depends.
why did it crack....
standard practice ya say....
all that means it's the "cheapest" way out... and leans more to a hack repair...
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming
WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
I'll often "fix" hairline cracks in drywall with caulk. Especially the ones that grow and shrink seasonally. Joint tape will not keep the house from moving. Of course, I tell the customer what I'm doing and that it's not a permanent repair.
However, hairline cracks on inside corners are rare because the joint tape usually pulls away before cracking. I even saw a corner once where one wall had dropped 1/2" and puckered the joint tape along the whole corner without cracking.
Check to make sure that there's joint tape in the corner. Check for any movement. It's possible that there's a missing nailer. If you re-tape (which is probably what's needed), prime the area first to give the joint compound a better grip.
