That's not true. There are a number of "blanket commandments" in safeguarding - especially "do not keep a child's secrets":
Always share your concerns, don't work alone, don't assume you know the whole story. The depending on the context is always there - at school level, on referral to SSD, at the investigation level if the referral meets the threshold and right up to court action
What we don't tell teachers is that there's "a context" for them to consider about gender questioning children. We tell teachers that they're part of a structured framework to protect children and that their role is to refer anything of concern to the DSL and then the DSL acts. Often with agonised discussions with SSD colleagues about backgrounds and thresholds - fully aware that a failure to intervene can lead to a child being harmed or an over zealous referral can alienate parents .
My comments are not a "gotcha" as you suggested upthread. They're an informed comment based on years of safeguarding in schools & local authorities to someone telling posters that in safeguarding "I think blanket commandments are potentially dangerous" or when talking about a year 8 girl wanting to change pronouns "The teacher decides to leave her to it for a couple of weeks, in which time she drops it".
Safeguarding in schools is a statutory duty with legal requirements and processes aimed at ensuing the safety of all children.
