We don't use top-level const in the project as a whole; generally harmless to
use but we rely on `const_cast` in some places to cast away `const` in a number
of places and if the original object is declared `const`, that's UB, so there's
ever-so-slight risk for top-level `const`. (Someday, I'd love to see our const
correctness get to the point where we use top-level const to enforce
correctness!)
