I personally have never used Kerberized NFS (we're an AFS site), so I'm
not really the one to comment on what enctypes NFS requires.  I don't
track NFS development at all.  But if NFS is no longer limited to DES,
it's very likely that it now supports the full range of standard Kerberos
enctypes, in which case the right thing to do is to just leave off the -e
flag completely and let the Kerberos infrastructure use whatever its
default configured enctype list is.
