I know why classical traditional television sets used over-scan back in the day, but with the modern models of HD-TVs we have now, why is overscan still a thing? I had always assumed that it would be dropped with the transition to HDtvs.

Because until ten years ago, you could still buy CRT HDTVs.
CRT = needs overscan to prevent part of the image not being visible. This doesn't magically change when you crank up the resolution. PC monitors made this clear with "X inches viewable" in their spec sheet, which is just the area reserved for overscan.
It also maintains compatibility with SDTVs through converter boxes. Don't forget how many old people are still running those.
Finally, we're only talking about 5% of the screen data lost. It's not like you're bumping 1080p down to 480p
Finally finally, all you have to do to get rid of overscan is change your TV's input type to PC. That automatically gets rid of any scaling issues, and gives you max resolution.
My relatively new 4k TCL still has it. I have to go in and adjust every resolution using it as a monitor with the Nvidia control panel to have the UI on everything fit properly. Its not that hard but just "Why?".
You should be able to change the input type to PC, and the TV will treat it as 1:1 with no adjustments required.
Both my 2011 LG LCD TV and my 2017 LG OLED both do this fine.
The picture quality is amazing for a TV this price but it has basically no options menu to adjust anything. Price you pay for a 55" 4k TV for $300.
Oh, gotcha, that's one of those Roku TVs that even treats the TV Tuner as "Roku channels," right?
Works great for anyone who doesn't tweak a single thing on their TVs. Well, I'll have to remember that the next time I buy a new set.

Depends on the model also a lot of the deeper setting for calibration are only available on the Roku phone app to control it with.
As in a lot of areas of life, after awhile conventions take root. Broadcasters are used to not worrying about lack of sharpness and clarity at the edges. TV manufacturers, as a result, go along with it.
