Sqlite3 - Generate more type of statements during initialisation

[JonathanFoo0523]

At initialisation of sqlite3 db, sqlancer insert random number of different sql statement specified by

private static int mapActions(SQLite3GlobalState globalState, Action a) {
        int nrPerformed = 0;
        Randomly r = globalState.getRandomly();
        switch (a) {
        case CREATE_VIEW:
            nrPerformed = r.getInteger(0, 2);
            break;
        case DELETE:
        case DROP_VIEW:
        case DROP_INDEX:
            nrPerformed = r.getInteger(0, 0);
            break;
        case ALTER:
            nrPerformed = 0;
            break;
        case EXPLAIN:
        case CREATE_TRIGGER:
        case DROP_TABLE:
            nrPerformed = r.getInteger(0, 0);
            break;
        case VACUUM:
        case CHECK_RTREE_TABLE:
            nrPerformed = r.getInteger(0, 3);
            break;
        case INSERT:
            nrPerformed = r.getInteger(0, globalState.getOptions().getMaxNumberInserts());
            break;
        case MANIPULATE_STAT_TABLE:
            nrPerformed = r.getInteger(0, 5);
            break;
        case CREATE_INDEX:
            nrPerformed = r.getInteger(0, 5);
            break;
        case VIRTUAL_TABLE_ACTION:
        case UPDATE:
            nrPerformed = r.getInteger(0, 30);
            break;
        case PRAGMA:
            nrPerformed = r.getInteger(0, 20);
            break;
        case CREATE_TABLE:
        case CREATE_VIRTUALTABLE:
        case CREATE_RTREETABLE:
            nrPerformed = 0;
            break;
        case TRANSACTION_START:
        case REINDEX:
        case ANALYZE:
        case ROLLBACK_TRANSACTION:
        case COMMIT:
        default:
            nrPerformed = r.getInteger(1, 10);
            break;
        }
        return nrPerformed;
    }

Is there any reason we don't generate statements such as CREATE_VIRTUALTABLE and ALTER during initialisation? By changing ALTER to be generated r.getInteger(1, 10) times, and add expected error for check constraints, we could generate more diverse statements.
