The UseMetaFD option is not to be set by laymen, so there are no layman's terms for it :).

What it does is change the way file descriptors are distributed among processes.

You should definitely worry about it being disabled.  The option is only still present for tuning and development purposes - basically, to see if the strategy we currently use ever has problems with new or different hardware or operating systems.

Things might work OK for a while with this option disabled, but be aware that the developers don't test in that configuration at all and the ability to disable it may one day disappear.
