Not sure if roaming is actually the fix for this problem. For whatever reason my Ring cameras just love connecting to the worst and most far away AP in my house.
I had to solve a similar issue for some crap IoT lights that would join the incorrect AP after a power cut every time.

That can mean that the portable wifi speaker-widget (which itself doesn't need much bandwidth) might go from working fine on the back deck or well-enough about anywhere else in the yard, to not working at all outside.
Which is normally a good thing to push the clients to roam to a better AP, OR you walked out of the building and want you phone to disconnect. But yes, does impact overall coverage area size.
Meanwhile: As a practical matter, shrinking coverage means "Hey, honey! I fixed the TV!" gets met with a response like "Oh, so that's why I can't listen to Audible on the veranda anymore!" :)
Obviously only if your honey is the type that enjoys being experimented upon (So long as it isn't mean, I like thoughtful attention like that, but some might not).
I need my TV to rapidly switch APs in very heavy load wide area networks with thousands of devices while I'm cruising through the venue with my motorized couch and entertainment system.
Now I want to actually build that for GPN24 next week. Wouldn't use AndroidTV for that though.
