Even 10-15 years ago, proper serial ports were becoming extremely rare, but there are times when you need a proper one.
Around that time we resorted to pc card/express card serial ports for occasions when USB to serial isn't good enough, although they were relatively expensive (3-4 times more than a USB serial dongle).
(The use case in that scenario was field engineers connecting to a very wide variety of odd equipment, like fire alarm panels and door entry systems, that sort of thing - USB dongles were massively inconsistent and unreliable - different dongles would be compatible/incompatible with different kit, was a right mess).
Obviously, these days, express card slots are also quite rare.
(The alternative is hauling out my old IBM T22, which I think maybe came with Win98... mostly still works apart from the battery).
If you're going into an RJ45 serial connection (like I am at the moment), then an ideal laptop would have multiple RJ45s which could be used as either 10G or serial with a standard cat5 cable (not a specially wired one).
Do any (non-specialist) laptops still have VGA ports? I had a quick look on the Dell site and couldn't find any.
Those are seems to available on other markets. https://www.asus.com/Laptops/For-Work/ExpertBook/ExpertBook-... https://www.fujitsu.com/global/products/computing/pc/noteboo...
Framework means in theory I could have a laptop (Well in theory) with say 4 ethernet / serial ports (switchable) and SDI, and that's far more useful to me than USB-C.

Some of my clients still have vt220 terminals with... serial ports.
Then you need a 9600 baud modem and rj11 wire of course, regularly in the corporate world or at your friends house.
So yeah, dongle it is. USB 1.1 dongle for sure, but still dongle.
