[SciPy-User] Welch's Anova (unequal variances)

Question out of curiosity

scipy stats has f_oneway which does the standard one-way ANOVA that
assumes equal variances across groups.
Similar to Welch's t-test, Welch's ANOVA allows for different
variances across groups.

I don't find anything with a Google search for "Welch's Anova in python".

Does everyone who uses ANOVA have data with equal variances across
groups, or is there something that google didn't find, or is everyone
using resampling methods?
