In my experience, at least some switches do not have any alternative.
I have used equipment that, as far as I can tell, cannot be set to drop
untagged frames.  (The closest it can come is to put them in an
otherwise unused, and thus not forwarded anywhere, vlan - but that (a)
is inelegant and (b) burns a vlan number (which on some of them has
been a precious resource; there are 4K vlans possible, but the switch
can often handle only a small fraction of that).)
