Here is a pre-coffee mockup via tcl. Put the below in a file called
fit.tcl inside your NUKE_PATH to be able to do something like this in a
knob:
[fit inMin inMax outMin outMax]
e.g.:
[fit 1 2 3 4]
proc fit {inMin inMax outMin outMax} {
return [expression "(curve-$inMin) / ($inMax-$inMin) * ($outMax-$outMin)
+ $outMin"]
}
It should be easy enough to extend this to automatically find inMin and
inMax.
And of course you could do the same with python, but tcl feels more
efficient for this.
Point is, it'd be great to have a default match expression to do this :)

Sorry, I forgot the second step. The below only normalises, after that
yo'd want to remap it to a new min/max, e.g.:
(curve-inMin) / (inMax-inMmin) * (outMax-outMin) + outMin
That combined into a fit function would indeed be nice to have as a
default math expression (so no tcl/python scripting is required).
Speaking of: is it actually possible to user define new math
expressions? That would be very cool!

I think Chris isn't referring to the knob layout but to an expression
function that kinda does the opposite to lerp, something like
normal(frame)
Something liek this:
(curve-_min) / (_max-_min)
Is that what you are after Chris?

I ask because, as a user myself, I'm also a bit frustrated with how
Nuke lays out it's knobs.

Does a fit function exist for knobs? Something akin to
Houdini’s fit or fit01 for remapping values to a normalized or
user defined range?
I looked through the knob expression doc and found just about
everything else I might want and perhaps I missed it so I
thought I might ask.
Best,
Chris
