Pg_stat_monitor paln option guc registration

PostgreSQL pg_stat_monitor
1

Hello,

I am using pg_stat_monitor. I need explain information, so I am using it after activating the option.
I would like to register guc to activate the general plaintext part with various options.
Is there a reason why this option was set as default and not removed as a guc option?

This is the part below.

static char *
pgsm_explain(QueryDesc *queryDesc)
{
	ExplainState *es = NewExplainState();

	es->buffers = false;
	es->analyze = false;
	es->verbose = false;
	es->costs = false;
	es->format = EXPLAIN_FORMAT_TEXT;

	ExplainBeginOutput(es);
	ExplainPrintPlan(es, queryDesc);
	ExplainEndOutput(es);

	if (es->str->len > 0 && es->str->data[es->str->len - 1] == '\n')
		es->str->data[--es->str->len] = '\0';
	return es->str->data;
}
