Makes absolute sense 👍

@tomneedham please backport

[PVince81]

@tomneedham backport still pending

[PVince81]

@tomneedham missing backport

[DeepDiver1975]

This is already in 10 - we want it in 9.1? 9.0? @PVince81

[PVince81]

sounds critical enough for a backport to 9.1 at least.

[PVince81]

ok so, 9.1 will be EOL soon... removing backport label
