And which ones would those be? The Giyo pump? The Beto Double Headed pump? The Schwinn Telescoping pump? The Zefal Air Profil pump? The Bell Airstrike? Or, perhaps, the Bell Telescopic? All 6 a capable of pumping up either valve and all 6 are available at Walmart for less than $30. Many of them are available for less than $10. I didn't see "lots of pumps on for sale that do NOT have any way to pump up a Presta valved tube." In fact, Walmart doesn't list a single pump that doesn't pump up both types of valves.

Dunlop valves were standard in the UK for a long time on everything but out-and-out road bikes. One still sees plenty of them on old bikes that are still in use.

I think this is something that needs to be eradicated like the smallpox, same with the English unit. it makes no sense to have to buy the same damn tools twice, now does it?

valves can get bent out of shape too easily for my taste.

As a kid in UK I used to ride my bike to go fishing. I always found that the rubber tubing for a Woods/Dunlop valve that came with my patch kit was useful to attach a fishing float to the line!

I have a topeak floor pump that came with a Dunlop adapter:
https://www.topeak.com/products/Pumps/trk_bl03
I do seem to be able to pump it up without the adapter but the adapter does give a bit more secure fit.
My Workcycles Transport bike came with Dunlop valves. When the front tube got cut somehow, I replaced it with a tube with a Schraeder valve, which fit the rim just fine. So far the back tire hasn't punctured. A good thing too, because getting that back wheel off is no joke!

The usual way I use them is,
unscrew the plastic cap, then the large nut just below it(holds the valve core in place). this lets all the air out.
next unscrew any nut at the base of the valve; so you can push it out of the rim.
dismount tire, pull the inner tube out.
toss it in the trash.
reinstall and reinflate tire with a shraeder valve tube.

The Dunlop/Woods valve combines the worst features of Presta and Schraeder with the best features of neither.
Dump it.
