They can be useful for various things:

1) for diagnostic purposes (e.g., assessing normality assumptions),
2) they can provide an estimate of the treatment effect in particular studies (that not only takes the observed effect from the study into consideration, but borrows information from the other studies),
3) there might be circumstances where one uses the BLUPs as predictors for other things (in a two-stage type of analysis).
