It depends what the file ’path/to/channels-wo-guixrus.scm’ would contain. :-)

My point was just to say that this speculative “ignore-channels” could
already be emulated using “guix time-machine”.  From my understanding of
what this speculative “ignore-channels” would do.

BTW, please note that this operation “ignore-channel” would be costly
because at least one “Computing Guix derivation” is required.
