Putting something in a spec does not automatically make it true. In the real world if you repeat expensive queries more than an undefined amount you get blocked or at least bot-checked.
Why the snark? The existing methods have been around for ages. Many engineers I’ve encountered were not even aware that there was a distinction between “idempotent” and “safe” as attributes of a method and generally conflated them, using “safe” in the sense of the dictionary definition instead of the spec’s.
Elsewhere it was suggested that we can now replace POST with this query. I was trying to be cautionary because just changing the method alone will bring different behaviour. I did so in brevity because I was in a rush. IMHO, that does not call for snark.
