Think of it as a tool in the utility belt.
same with wet trim vs dry trim or choping down to nugs or branches... each will impact the length of time it has to dry.
in a naturally humid environment, it may be overkill or even risky to extend drying times. If in an arid region, it may be necessary to have a proper drying legth.
Slower is thought of as better, but at some point it's so slow you'll just grow mold.
So, i'd answer your question with more questions - rhetorically. Whats your average dry length? Do you want it longer? if so, then hanging a whole plant should help toward that end.
If you have upper 60s F and 60% RH, even trimmed buds on a mesh rack will take ~9 days. I get that with wet trimmed buds in a mesh rack in 68F / 60% RH. I grow in the winter, so a humidifier is necessary to keep the RH% steady.
