I think removing apostrophe is fine why remove 1.75u space? I feel like some people do use it
As far as I know, 1.75u space is only used on three 40% boards (JD40, Daisy, Vortex Core), which are quite rare to boot. Not only that, but I think the most popular out of those (JD40) actually uses not one but two 1.75u spacebars, so a single 1.75u spacebar doesn't do much in the grand scheme of things.
Someone please correct me if I'm wrong.
