I thought of it but couldn't think of any good use for it so I decided
to go with 'uint'. Is there a compelling reason for it or can we add
it later if we should need it?

The conversion to MeshFunctions is practical since it means we can
plug it directly into the assembler which relies on MeshFunctions for
checking the subdomain number of the current cell or facet. It might
be possible to do it the other way around, iterate over subdomains and
assemble on each, but that requires a rewrite of the assembler.

For boundary conditions, the conversion is not necessary.
