I think they should be pure as much as I think they should be const.
The reasoning is analogous for both.
We have immutable class instances that want to provide the methods =>
make them const.
We have pure functions that want to provide the methods => make them pure.
This reasoning is not taking into account the whole picture because
We have implementations of those methods that want to use non-const
methods in their implementation. (eg. database connection)
We have implementation of those methods that want to use non-pure
methods in their implementation (eg. database connection, logging)
The essential difference is there's no "pure" object, so there's no
motivation to plant "pure" on its methods.
