Wrong HINT during database recovery when occur a minimal wal.

Hello hackers,
When I do PITR in a strange step, I get this FATAL:
2021-01-15 15:02:52.364 CST [14958] FATAL: hot standby is not possible because wal_level was not set to "replica" or higher on the primary server2021-01-15 15:02:52.364 CST [14958] HINT: Either set wal_level to "replica" on the primary, or turn off hot_standby here.
The strange step is that I change wal_level to minimal after basebackup.
My question is that what's the mean of [set wal_level to "replica" on the primary] inHINT describe, I can't think over a case to solve this FATAL by set wal_level, I cansolve it by turn off hot_standby only.
Do you think we can do this code change?--- a/src/backend/access/transam/xlog.c+++ b/src/backend/access/transam/xlog.c@@ -6300,7 +6300,7 @@ CheckRequiredParameterValues(void) if (ControlFile->wal_level < WAL_LEVEL_REPLICA) ereport(ERROR, (errmsg("hot standby is not possible because wal_level was not set to \"replica\" or higher on the primary server"),- errhint("Either set wal_level to \"replica\" on the primary, or turn off hot_standby here.")));+ errhint("You should turn off hot_standby here.")));
