on a factor (see 'group' below). Is such a thing possible?

I agree that glmnet is old and reliable. One might want to use a
tidymodels wrapper to create pipelines where you can more easily switch
among predictive algorithms (see the `parsnip` package), but otherwise
sticking to glmnet seems wise.

Which confint() method do you have in mind? There is at least four of
them by default in R, and many additional classes could make use of
stats:::confint.default by implementing vcov().
