Oh!  I'd not thought of that, but yes that is a plausible near-term
requirement for readfuncs support for utility statements.  So my
concern about suppressing those is largely a waste of effort.

There might be enough node types that are raw-parse-tree-only,
but not involved in utility statements, to make it worth
continuing to suppress readfuncs support for them.  But I kinda
doubt it.  I'll try to get some numbers later today.
