Clear type is sub-addressing the RGB by colouring the edge pixels. Regular anti-aliasing uses whole pixels and is separate from Cleartype. Also at sufficient resolution the screen doesn't need AA. There is ALSO font hinting, which on Linux can usually be off, medium or aggressive. These are three different things.

Anti-aliasing and hinting existed before MS Cleartype. As did desktop publishing on Mac OS before Unix based OS X, Gem, Win 3.x, UNIX/Solaris systems and even CP/M.

Cleartype was introduced only in 2001 on XP and was off by default. A later powertoy let you tune it on XP. On by default on Vista.
It and similar systems must be "tuned" for the actual digitally connected panel in use and not all are suitable.
You can certainly have whole pixel anti-aliasing and it existed even before IBM PC was launched! C code was published for anti-aliasing (which apples to text and graphics) before Windows existed.

Font hinting is a separate thing. Not all fonts have it.

Look it up.

Kindles need font hinting. Look at what happened when Amazon removed hinting from Bookerly.

Didn't equate them, i said that it's a noticeable/readily discernible difference, making sense given the multiple pixels involved for every single "logical" one.
You are by all means free to test this out yourself with a modern font, ie one designed to be antialiased from the getgo.

Not sure who told you it's a pseudo-increase, but we may agree to disagree

Likewise for its only ever been needed on lower res displays..? I'd say on the very contrary, you need some decently high res before you can be the judge; try the nano texture 7,5K apple monitor. With and without subpixel AA.

Then get back to me, shall you?

As to retina mode "always on", i assume it depends on one's personal experiences/devices used? If locked?
I've found a healthy number of readers and viewers where this is controlable, from free ones to highly expensive ones.
