As I'm sure most of you know, leaving your laptop plugged in and

No, it isn't. Where did you get that idea?
It's very harmful if you're using a charger which doesn't figure out
when the battery's full and switch to trickle charge mode but just keeps
dumping full charge power in - you'll kill the battery in short order
and, if you're lucky, set stuff on fire too. However, I know of not a
single laptop ever shipped with such a dumb charger. All laptops have
smart chargers, which sense when the charge is complete. Leaving the
laptop plugged in while fully charged is a perfectly normal use case
that all manufacturers expect and design for.
I'm not going to pretend to be a professional when it comes to
batteries, but my battery was recalled about two years ago for setting
stuff on fire. Now you know of one.
