Let me clarify that I'm not against flexibility or giving users control
on the processes.
It's not about choosing between no control and full control. Is finding
a balance where a UI provides the necessary tools for the regular job
without hindering the possibility of experimentation.
It's extremely difficult to create a UI that both exposes every possible
user and provides a fast and comfortable workflow.
Adding checkboxes and buttons for every need doesn't solve the issue.
Pretending that you can separate the "basic" and the "advanced" users in
two simple groups by providing insufficient tools for basic users and
the cluttered UI for advanced ones is not going to result in a good
tool.
Nodal UIs aren't perfect, but provide a good balance because every tool
is an individual node, and power and flexibility come from combining
those nodes.
In this case of linear vs. perceptual, a gamma node would allow to turn
every operation in a linear workflow into perceptual.
Notice how different is the paradigm: a single tool that changes how
other tools act instead of adding an extra option to every single tool.
And a tool that is added on demand, only people who want to use it will
be exposed to it, and the rest wouldn't be disturbed by a cluttered
interface.
Unfortunately, the UI paradigm in GIMP and similar applications makes
this really difficult, because it's inherited from a time where all the
operations were sequential and destructive.
Again legacy stopping progress.

Part of this is a UI problem, and adding buttons or checkboxes for every
possible alternative isn't a good way to design UIs.
