I don't think it's a problem - In my experience panthers poof - but my flapneck and jackson take a while more to shed -and the older they get the more time it takes. I've read of people having problems if the old shed is cutting off blood flow to a tail but that doesn't look like it's the case. I try and give mine a little extra spraying when they are sheding - I don't know if it makes a difference (I do know it makes my panther give me a dirty look- but that's his way, he really loves me-ha)
