I imagine Marc Levine will have a comprehensive answer for you... but from
my angle:
The value of the linearization function is to reduce reprofiling by allowing
you to correct the baseline underneath a profile. If you have device
linearization capabilities, and they do the job properly, then you will have
a stable base line without profile linearization.
If its not needed, I would avoid profile linearization (especially for RGB
devices), for a few reasons. Profile linearization adds a set of 2d curves
onto your 3d LUTs in the profile. This can be helpful when needed, should be
avoided when not needed, as each added layer of correction adds a twist to
the process. Some devices and software may have conflicts with profiles
incorporating curves, or not accurately softproof them.
