Not hardly. My excuse is severe arthritis in both hands which limits my playing massively even on a 4 string. Plenty of other reasons for not being able to get around on the average five. How are you on upright bass, for example?

As someone that had their left hand bolted back on with a titanium plate, plays five strings and upright bass I can tell you that with the correct technique anyone that can play a four string could do five strings, if anything I play with a more open hand on a five string even though I do still grab the neck far to hard, my classic 5 Stingray nut width can't be more more if at all that some P basses either.
I've seen many people swap to five strings BECAUSE of their arthritis to use the playing across the board technique to make it easier on their hands, fingers and arms.
