Review comment (bug):
In commit "kernel: De-globalize fReindex" (9b2c9c2fce32fe858d1361e863c72108a384a5c8)

It seems like there is a prexisting bug here, and the `f_wipe` argument passed here should be `blockman_opts.reindex` instead of `chainman.m_blockman.m_reindexing` or `fReindex`. Otherwise if the node is restarted before reindexing completes the TxIndex will be wiped a second time?

Same for BlockFilterIndex and CoinStatsIndex below

Code after:
            } else {
                return InitError(error);
            }
        }
    }

    // As LoadBlockIndex can take several minutes, it's possible the user
    // requested to kill the GUI during the last operation. If so, exit.
    // As the program has not fully started yet, Shutdown() is possibly overkill.

        LogPrintf("Shutdown requested. Exiting.\n");
        return false;
