     *  some of them requires other member initialized.
     *  For example, constructor `quorumManager` requires `bls_worker`.
     *
     *  Some objects are still global variables and their de-globalization is not trivial
     *  at this point. LLMQContext keeps just a pointer to them and doesn't own these objects,
