Easy to use, but (as I mentioned) that would prevent the possibility to
re-hardcode only some of the standard data; if we wanted that, the
canonical data (nfc.nrm) would be the primary one, while keeping
lesser-used data loaded from a file.

I would also like it to be easy to get the standard data with other modes,
such as canonical+FCD or compat+casefold+DECOMPOSE.

Dead-easy-to-use would be to fold both the data file and the mode into the
specific function:
  getNFCInstance()
  getNFKDInstance()
  ...

but that seems like a lot of functions (5), and it would keep canonical+FCD
and such on the existing, harder-to-use API.

That's why I came up with the proposal the way I wrote it...
