Well, SLIME's fuzzy is older than that, for example.  So age
is not a major factor factor here. Also, the current behaviour
was adopted when there was NO flex in Emacs.  If there would
have been, the decision would have been different, IMO.

I'm very happy that you find it usable. However, I have the
conviction -- what I've been trying to persuade you of that
conviction -- that it is _more_ useful for the remaining
population of existing flex users _when_ it has the highlighting
I propose.  If you take one of my proposals, then you, as
an individual from a new population of flex users migrating
from 'prefix' can still customize it to adhere to your longstanding
'prefix' habits. Or you can adapt to what I think is the majority's
use of 'flex'.

Again, I must stress that the latest proposal is NOT a change in
defaults because the people starting out emacs with no settings
whatsoever would see _absolutely_ no new behaviour.  It is only
people that _enable_ the new matching style 'flex', which I
implemented some months ago, that would see the highlighting
the way I propose it.

I will, as I have already done, concede that it is a change in what
you and others have called "consistency" between matching styles.
I have explained enough, I think, why I think this isn't a big problem.
But in any case it is NOT a change in defaults, unless you are
considering that there is already a large number of 'flex' users
tracking the Emacs master branch between some months ago and
today that rely on it functioning the way it does.  I do not think that
is the case.

(Note, to avoid a frequent misunderstanding, that I'm talking strictly
about my latest 2 proposals, alright? the "renames" one and the
"new-face-just-for-flex".  Again I did indeed propose earlier a change
in defaults, which I abandoned.)

Also, as another data point, you need not travel beyond Emacs-land
to see examples that corroborate my vision. You needn't even travel
farther than GNU ELPA, I believe.  Company's tooltip behaves like I
describe, and so does Ivy.  A little farther you have Helm, an extremely
popular extension, and SLIME, and SLY.
