The problem is this reason doesn't make sense. N.B. I agree it's an acceptable trade-off for ‘guix substitute’, which has different operating parameters. When I run ‘guix weather’ twice in a row, I am *never* interested in reviewing the stale numbers I got the first time (or worse: a mix of stale and new numbers). I don't care if the data is very fresh: I am asking for fresher. Caching is never to my advantage: it is ‘saving’ only the work I asked it to perform, against my wishes. ‘Look how fast I fed you possibly bogus data against your will!’ is not an impressive boast. Is my concern clear? Reasonable? Kind regards, T G-R
