Unicode allows for  1,114,112 different glyphs, excluding variants.
with variants, you are looking at roughly 1,750,000 glyphs.

Taking, thorn, for example, with the current setup, one knows to look in
the Runic range. when the sub-range is at the whim of a programmer, it
could be literally anywhere.

Under what circumstances would one be using glyphs they know not the
name of?

The claim is that the  current filters are inadequate. Thus, the need to
dummy it down, so that it is less efficient, more time consuming, and
awkward to use. But because less glyphs are displayed, Joe Sixpack
thinks it is easier to use.

Obviously that is going to happen. That is the desired and expected
behaviour.  To do otherwise would constitute a show-stopping bug of the
highest possible priority to fix.

Those are variants, and are part of the Unicode specification.
If font creators correctly implement the full sub-range, those variants
would be included, but since, for various reasons, won't implement the
full sub-range, the variants are omitted.

The Unicode Specification.
