Xorshift128+ is not a cryptographic rng though, so at least this isn't a cryptographic attack...

Should programming languages use cryptographic rngs like a ChaCha20 based one in their standard libraries to stop accidental use of non cryptographic rngs for cryptographic purposes? But that comes at the cost of speed

No. Sometimes you want a reproducible PRNG sequence. These efforts to harden generators break the existing specifications with a rug pull.
