I'm OK with that.  Perhaps a positive option --allow-group-access would
also be useful.

Do you want both --allow-group-access and --no-group-access options to
be added to pg_basebackup?

Without --allow-group-access is automatically --no-group-access?

Or you want pg_basebackup independently decide the group access irrespective
of the source directory?

Even if the source directory is "not group access", pg_basebackup --allow-group-access
make it standby as "group access".

source directory is "group access", pg_basebackup --no-group-access make it
"no group access" standby directory.

Default behavior of pg_basebackup is just to copy same as source directory?
 
Let's make sure the behavior of these options is aligned with initdb.
And write tests for each variant.

OK.
