So what I'd be missing in Argyll would be a perceptual intent just as the one in ProfileMaker because
a) this makes it less prone to clipping
b) just "looks" more correct to my eyes; a mapping to L* 100 seems to make the image artificially bright when compared to the scanned original

That's not the sort of workflow Argyll is intended for. The assumption is that for minimum confusion, input spaces are colorimetric, so that a coherent one step gamut mapping can be done from source gamut to destination gamut, either in creating an output profile or a device link. Throwing some sort of perceptual transform into the input profile is rather un-defined, since the output space is unknown at that point. It's also altogether cleaner to relegate user preference adjustments to a separate step in the workflow (eg. abstract profile), so that the device profile doesn't have to be re-built every time the user changes their preference.
