Neat, thanks for the update!  (I pushed it on your behalf because you’re
not currently authorized in maintenance.git; please email guix-sysadmin
if you’d like to be there.)

I wish they had opted for something more expressive (and also with a
more meaningful name :-)) than ‘outputHashMode’, similar to what you did
for ‘guix hash -S’.  But anyway, it does the job!

It looks like SWH will be storing nar hashes; will there be endpoints to
query directories by nar hash?

Thanks,
Ludo’.
