This is true. This is also irrelevant if nobody actually does it. My nexus 7 tablet survived 6 years with a dead battery due to having qi charging. For every phone I've bought since then, I have searched for charging cases and not found even a single one at the time. This includes the moto e2, moto G5, moto G6, and my current Samsung phone (a32 or something, can't recall at the moment; it's the free T-Mobile 5g phone). Basically I wanted something that ideally supported wireless charging, but at minimum was semi-permanently attached to the charging port (charger built into the case itself to protect my port).
