Should we add a field for quality of evidence, or similar?

We have several metrics that could be used to indicate high vs lower-quality phenotype-locus associations. For example, the number of cases reported, pathogenic genotype frequency, etc.
Would it be useful to have some kind of field that indicates loci that should potentially be excluded from downstream analyses? I'm thinking in particular of DMD and POLG.
Also, a better way of flagging mendelian vs modifier loci?
