[Questions] Can percentile_doy be refactored to use xr.quantile?

• Python version: 3.12.8

Context

I am trying to use percentile_doy to compute thresholds for hot_spell_frequency. I am encountering a few issues there so I started to look into the implementation of the function and saw that it implements its own percentile computation, which made me wonder whether this is still necessary or maybe coming from a time before xarray was offering the quantile computation. I see that the default behaviour is different but since both functions allow the quantile computation method to be configured I imagine this change could be performed without changing the behaviour? Unless, there is something in this function xr.quantile doesnt do?
