I like your idea in your other mail where you suggest to actually
use foo-supply and bar-supply names in the simplefb node, and then have
some code simple iterate over all the properties and check for *-supply
properties, so that the proper, schematic matching names can be used.

But surely if we go this way having a helper for this so that others
can re-use that likely not entirely trivial code is a good idea ?

Yeah.  It's trying to come up with a way to do this that is easy to
avoid abuse that's tricky.

One user which comes to mind immediately here is the generic mmc-pwrseq
driver.

I agree that we need to be careful to not use a helper like this too
much, but I do believe it will make sense to have it in some rare cases.
We can put a big warning in both the header declaring it and above
the implementation to use it scarcely.

I'd rather have something that was visible in the code, not everyone
reads the documentation especially not subsystem maintainers reviewing
drivers that use APIs they're not familiar with.
