As my post says "FROM MY EXPERIENCE" and "YMMV" and never do I say "My advice is..." or "it is OK for you to do it because I do it" - can you see the difference in a person relating their experience vs. giving advice for everyone as you do? Since it seems you don't have that experience of accidentally or on purpose having your supplies or kid (for the past 14 years wearing a cgms) go through the various detectors, you can't really speak to it.
I have a problem with posters who aren't considerate of others' experiences, are condescending, and belittle their sharing of it because they disagree with it. Complain to
@SueM in MN if you think my post is inappropriate.
My experience of actually doing it is as valid as you relating a conversation with a
single Dexcom tech you had "years ago"even if the tech may have changed in the meantime.
Back on topic - Dexcom itself says this for their newer G7 for anyone who uses it:

Can I wear Dexcom G7 through security or while flying?
At security checkpoints
You can wear your Dexcom G7 sensor when going through walk-through metal detectors and Advanced Imaging Technology (AIT) body scanners. Alternatively, you may ask for hand-wanding or a full-body pat-down and visual inspection. Ask for visual inspection of any part of your Dexcom G7 in the baggage scanning machine.
Most security check points require you to temporarily give up your smart device* and receiver.
Dexcom G7 is safe to go through luggage scanning and will not affect product
