I totally think that the current implementation needs to be improved. It is currently not a care-free, best-practise feature to have must-staple on your certificates.
You can do it, but then you have to monitor for OCSP responder errors in your server logs (which I do daily, not that difficult fgrep cron job). If you need safety above the added performance of stapling, turn it off. If you can live with a little risk (and the LE OCSP responders usually work nicely), maybe you turn it on.
