It is possible to support both vanilla and modified syntax in the same file. The
revised syntax is supported in ocaml.vim using the `ocaml_revised` variable:

~~~~
if exists("ocaml_revised")
 syn keyword  ocamlBoolean  True False
else
 syn keyword  ocamlBoolean  true false
endif
~~~~

As you pointed out, it is also possible to fork the syntax file and have a
different filetype. I started this way. You can use the
https://github.com/raphael-proust/ocaml_lwt.vim repository and edit the
`ftdetect/ocaml_lwt.vim` to trigger the fitetype only for .mlw (and .eliom?)
files:

`au! Bufread,BufNewFile *.mlw    set filetype=ocaml_lwt`
