Throughout nearly 20 years of owning a laptop of some description (often two, a personal and a work-provided machine), I've always had to carry some set of dongles of one type or another.
Which is absolutely true - there are still people who could make good use of a VGA port for giving presentations in meeting rooms that were state-of-the-art in 1998. (At my previous workplace, HDMI projectors appeared at just about the same time that Apple dropped HDMI from the MBP... D'oh!). Personally, I'd prefer a laptop with ethernet, too - but 2012 called and asked for their whinge back. Some people use CF cards... but you have to draw the line somewhere. Most of us have already accepted that a 1987 VGA connector doesn't belong on a modern laptop.
The debate is really over where Apple have decided to draw the line, and the connectors in question are things like HDMI, SD and USB-A which are all relatively modern, slim connectors (cf VGA/DVI/Ethernet/CF) that other manufactures manage to fit into sleek, modern laptops, and which still feature as the main interface on brand-new peripherals. Apple is trying to declare them "legacy" when they simply aren't.
The other reason for resistance to USB-C is that - with the exception of some of the new Thunderbolt 3 capabilities - USB-C didn't improve on USB, DisplayPort, HDMI in the way that (say) HDMI and DVI offered far higher quality displays than VGA, or TB 1/2 offered significantly faster speeds than USB3. USB over USB-C is still the same, single USB 3.1 stream as you'd get from a USB-A port (and, yes, 10Gbps USB3.1g2 does work on USB-A). Your multi-port adapter is running GB Ethernet, SD and USB 3 off a single USB3 stream (or, if its configured to support 4k video, make that a USB 2 stream as USB-C can't carry 4k@60Hz and USB 3 at the same time). So for many people, there was no real upside in switching to USB-C.
With my 13" 2017 MBP, I just need the one USB-C multiport adapter and I'm covered. I carry fewer dongles around with me now.
You're obviously not the one in the party expected to bring enough spare dongles/cables for everybody (or supply them to visitors). As far as I'm concerned VGA dongles are a consumable
