It was backported into 6.18 stable (in v6.18.14) and in 6.19 (in v6.19.10).

FYI I haven't tested that, but it should fail on 6.18.0..v6.18.13 and on
v6.19.0..v6.19.9 due missing backport.

I'd assume that's correct, because on stable/LTS we should IMHO be more strict
to ensure it behaves as expected. WDYT?

Kind regards,
Petr
