The other side of this challenge is that the "technology" is mostly irrelevant for above-average applicants with solid CS chops.
I apply for lots of jobs featuring technologies I haven't used (beyond toy personal projects or something in college) because I have a long history of picking up new tools and being productive in weeks or months at most - because I understand the underlying semantics of the tool regardless of its presentation, syntax, etc.
Keyword scanners (and humans focused on keywords) are unable to hire me for roles where I haven't used the technology (much) before - and I guess that's fine and well as I am indistinguishable on paper from someone who doesn't know what they're doing.
Just presenting it as another part of the challenge of both finding good people and for good people finding good jobs.
