Basically yes, if employers/customers only look for products and not general experience and signs of being a good crafts(wo)man it’s not useful.

On the other hand, someone who already worked with 10 Languages, 7 webframeworks and 5 deployment/config management tools plus showing good craftmanship has enough experience to learn one more of these quickly. Only for a short term gig, the learning/being productive relation could be disproportional.

I‘ve experienced it being habdled rather the latter than the former way and don’t remember not getting a job for having not yet worked with one of these tools, but bei g chosen for experience and quality work.
