Yes, for `FeatureTable[Frequency]`. See the associated documentation about the types I linked [before](https://docs.qiime2.org/2020.8/semantic-types/).

A quick [forum search](https://forum.qiime2.org/search?q=bray%20curtis%20RelativeFrequency) lands me on [this](https://forum.qiime2.org/t/rarefaction-vs-relative-abundance/16956/4), which suggests that you can not currently use `FeatureTable[RelativeFrequency]` as input into `bray_curtis`, as outlined [here](https://forum.qiime2.org/t/rarefaction-vs-relative-abundance/16956/10). So, for the moment, this metric still requires `FeatureTable[Frequency]`, i.e. counts.
