While they may be handy if you have a single key, once you start using
several keys, they mainly just get on the way.

It can't be simply removed though, as that could make some ssh clients
to stop working. I would make sure the same behavior can be achieved
with IdentityFile (it may need to be tweaked so you add keys
at the end), and then remove the native support, moving it to the config 
file.
