Hams should insist that the more exotic and costly new rigs have some
means of using an external monitor instead and as well as the built in
display panel. Personally I think trying to see a waterfall and RF
spectrum on the rigs displays is pretty useless, they need viewing on,
at the very least, a small computer monitor to be worthwhile. With my
HP8568B spectrum anaylser the display tube is obsolete and it's
getting harder to find good used replacements. However it also has a
monitor socket to run a separate, (and much bigger, if desired)
display, so all is not lost as it slowly darkens.

The industry standard dot matrix display is a great idea, but what
chance manufacturers agree to such a selfless act of kindness to us
end users? ;) Individuality has its costs...
