The method for keeping it made it quite difficult to fix this bug: 
https://github.com/mirage/mirage/issues/461 , which I think I'm not 
alone in feeling quite strongly should go away.  There's some discussion 
there which is relevant.
It hasn't yet been mentioned in this context, but the expansion of the 
number of backends we support gives us a good opportunity to reconsider 
whether it's a good idea to special-case the platform, also.  Soon we'll 
have people who are mostly using `-t ukvm` or `-t virtio`, and if we 
remove the deprecated --${MODE} before merging these backends, nobody 
has to rewrite or relearn them :)

They'll be mentioned on the breaking changes page for the 3.0 release 
(along with many, many other changes that are currently in master).  I 
can (and will) begin a branch to track these.
The functions in question are listed as deprecated in Functoria's 
documentation for some time, and have been removed from 
`mirage-skeleton` as part of "spring cleaning" a few times, although 
they keep creeping back in.
