Yes, I have asked the developer to update the doc for the EFFECTPLOT statement.
In general, the EFFECTPLOT statement supports fixed-effects for generalized linear models.

PROC LOGISTIC with a STRATA statement (conditional logistic regression)
The effect plot for the MIXED procedure only supports the fixed effects.
The RELIABILITY procedure in SAS/QC (but you can use the EFFECTPLOT statement in the procedure).
I do not know whether this list is comprehensive.
